Description Andras 2018-10-23 04:27:13 UTC
SUMMARY
KDEConnect fails to open remote phone directory as it says protocol died unexpectedly


STEPS TO REPRODUCE
1. Turn on Kdeconnect on PC and on Android too
2. Pair the two devices
3. In Dolphin, click on the name of the phone created by Kdeconnect

OBSERVED RESULT
The process for the kdeconnect://... protocol died unexpectedly

EXPECTED RESULT
Open given remote phone directory

SOFTWARE VERSIONS
(available in About System)
KDE neon 5.14
KDE Plasma Version: 5.14.1
KDE Frameworks Version: 5.51.0
Qt Version: 5.11.2
Kernel Version: 4.15.0-38-generic
OS Type: 64-bit

ADDITIONAL INFORMATION
Hi, I have this issue for a while now on Ubuntu 18.04 based KDE neon 5.14.1, QT Version 5.11.2, Kernel 4.15.0-38, kdeconnect 1.3.1-0
I try to access Kdeconnect through Dolphin what says:
The process for the kdeconnect://... protocol died unexpectedly
Anybody experienced similar issue? What could be the problem?
It seems everything else functional, I mean I get the notification and remote input, etc, the phone name appears in Dolphin, only directory access won't work.
Firewall ports 1714-1764 udp tcp implemented.
Tried several workaround, full reinstall, erase related folders, on android too.
I have to note, very rarely it come alive, for example when I installed an other Android app for ftp and connected to it with Dolphin. I was able the access the phone by rightclicking on the phone name given by kdeconnect (not the one connected with other app obviously) / edit and click on open file dialog and examining finished pop up message appeard. It worked only once. 
It's issue on two different desktop pc with same KDE neon OS and with two different phone.
Also I found this in journalctl for example:
kdeconnect.plugin.notification: Not found noti by internal Id: "0|com.samsung.tmowfc.wfccontroller|2131165186|null|1000"

Comment 4 Simon Redman 2018-10-24 17:26:14 UTC
Could those who are affected by this please do the following:

After experiencing the error, run the command:
qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp isMounted

And report whether that returns true or false, then run

qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp mountAndWait

Wait for the command to return, then check if browsing the phone through Dolphin works as expected

In the above commands, <deviceID> needs to be replaced with your actual device ID. This can be checked by running `kdeconnect-cli --list-devices`

If you don't have qdbus installed, any other dbus-poking program is equally useful. The GUI programs qdbus-qt5 and d-feet are nice too.
Comment 5 Andras 2018-10-24 17:55:36 UTC
For me, results for given commands above on two different PC with the same installation and with beta participation on Google's Play Store:

qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp isMounted
false

qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp mountAndWait
Browsing the phone through Dolphin still won't work

qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp isMounted
true
Comment 6 boingo-00 2018-10-24 19:28:39 UTC
> qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp
> isMounted
true

> qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp
> mountAndWait
0 files in dolphin
Comment 7 Simon Redman 2018-10-24 19:41:52 UTC
Well darn. I thought for sure that was the problem. If I think of something else to try, I will post again.
Comment 8 kskot 2018-10-24 20:18:15 UTC
I have the same problem with kdeconnect, isMounted and mountAndWait return both true. But I found that executing the command with getDirectories gives me the correct path all mounted directories of the devices (/run/user/1000/<device ID>/storage/emulated/0). I'm also able to access the directories and modify files in it.
Comment 9 Tommy Beauclair 2018-10-24 21:49:56 UTC
> qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp

true

> qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp

Same here

Empty directory in dolphin.
But after F5 - 2 entry: "all files" and "photos".
After each F5 press add also "photos".

If it's a suggestion to use F5 well, you can see it's not that simple problem that someone just forgot to refresh something. Thanks anyways.
Comment 13 bluelupo 2018-10-27 12:17:26 UTC
I have the same problems with kdeconnect see the bug report I opened under https://bugs.kde.org/show_bug.cgi?id=399943

I have verified this with two KDE Neon installations, both show the same error behavior.

Comment 14 Laosom 2018-10-27 17:09:31 UTC
Experienced only in KDE Neon, other distros and Kubuntu is fine.

kdeconnect-cli --list-devices
- Samsung GT-S7710: 104bfb976bc224ee (paired and reachable)
1 device found
qdbus org.kde.kdeconnect /modules/kdeconnect/devices/104bfb976bc224ee/sftp isMounted          
true
qdbus org.kde.kdeconnect /modules/kdeconnect/devices/104bfb976bc224ee/sftp mountAndWait          
true

Error : The process for the kdeconnect://104bfb976bc224ee protocol died unexpectedly.


Checked in terminal, and it seems to be mounted and can be browsed:

kdeconnect@192.168.0.103:/ 1048576000        0 1048576000   0% /run/user/1001/104bfb976bc224ee

Even with the path pasted to Dolphin.
Comment 15 Laosom 2018-10-27 17:15:59 UTC
Issue not fixed in Neon User ed. by the 5.14.2 update installed today.
Kubuntu 18.10  (with backports) on the same Plasma version is fine.
Comment 16 Erasmo Caponio 2018-10-28 12:19:06 UTC
I quote the Comments #14 and #15 of Laosom (neon 5.14.1 and 5.14.2). I don't know about other distros.
Comment 17 Nicola Jelmorini 2018-10-28 18:21:04 UTC
I can also confirm the issue on KDE Neon 5.14.2 with Dell XPS-13 and the device Google Pixel 1 with Android 9 (I don't know though if Kdeconnect depends on the Android version).
Comment 18 Simon Redman 2018-10-28 23:19:17 UTC
It looks like there is a common thread in these issues that everyone is running some Ubuntu-based distribution

Could everyone who is affected by this problem please post:

- The result of running the two dbus commands I describe in comment 4: https://bugs.kde.org/show_bug.cgi?id=400178#c4

- Whether or not you are able to manually navigate to the mount point and browse the phone filesystem after running the above dbus commands
You can find the mount point(s) by running `qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp getDirectories`

- Your system version information, as in the very first comment. Especially, make sure to include your distro and version (but all the other information might be helpful too)

Sorry that I don't have better news for you. Hopefully we can get to the bottom of this.
Comment 19 Andras 2018-10-29 01:47:50 UTC
For me it's even worse now as it was on my comment #5 above:
https://bugs.kde.org/show_bug.cgi?id=400178#c5

Previously it's mounted, now it won't mount either:
qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp mountAndWait
false

I'm not sure if it's count, I found these line during the process through jurnalctl -ex for example:
kdeconnect.plugin.sftp: Timeout: device not responding 
gdk_device_update_tool: assertion 'GDK_IS_DEVICE (device)' failed
UdevQt: unhandled device action "unbind"

Does running kdeconnectd under gdb give any extra output?

$ killall
$ gdb /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd

the 'run' at the (gdb) prompt.

Forget it if I'm wrong however I don't think placing whole bunch of common device and journalctl information would help the thread, it creates a mess.

> Sorry.
Now I feel bad. Although this place not for personal dialogue, excuse me if I was pedantic. I'd stuck with shorter posts but more info better than nothing and thanks for your comment Laosom.
Comment 26 Nicola Jelmorini 2018-10-29 19:17:59 UTC
These are the results of the suggested commands:

nicola@nicola-XPS-13-9360:~$ qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<device>/sftp isMounted
false
nicola@nicola-XPS-13-9360:~$ qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<device>/sftp mountAndWait
true

After the second command I still can't browse my phone content.
Comment 27 j12 2018-10-30 01:39:04 UTC
This impacts me too, but I think I found a workaround?


>qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp isMounted
true
>qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp mountAndWait
true

After running both of those I couldn't browse files via clicking "Phone" Dolphin or via the kde-connect browse-folder button. But I ran
>qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp getDirectories

and was able to `cd` to the directory reported and ls files there. On a whim, I copied the path into Dolphin and was able to browse my phone, open there as per normal. Opening and deleting also worked.

So it *seems* like the issue is kde-connect's integration with eg Dolphin instead of a problem with the underlying storage mapping.

For me the results for the requested commands are:

qdbus org.kde.kdeconnect /modules/kdeconnect/devices/<deviceID>/sftp mountAndWait --> true

Now I can see the folder structure and access the files via dolphin.

Comment 31 Andras 2018-11-02 22:54:49 UTC
Those who allegedly able to mount and access phone directories manually, please report your Kdeconnect version too. I was just hilariously frustrated why the hack it won't work for me till I just got kdeconnect 1.3.2 upgrade from 1.3.1.

Now my results are:
qdbus org.kde.kdeconnect /modules/kdeconnect/devices/0d78094f9d46e0b2/sftp isMounted
false
qdbus org.kde.kdeconnect /modules/kdeconnect/devices/0d78094f9d46e0b2/sftp mountAndWait
true
qdbus org.kde.kdeconnect /modules/kdeconnect/devices/0d78094f9d46e0b2/sftp isMounted
true
Now, I also able to reach phone directories through /run/user/1000/... with Kdeconnect 1.3.2.
However I think, it's important to note at least from the aspect of Plasma Desktop, Dolphin still won't access and it's still saying "protocol died unexpectedly".
Comment 32 Will Brown 2018-11-03 13:34:15 UTC
I am having the same issue as well, but only on Neon, freshly ran updates today. Issue is nonexistant on Kubuntu 18.10 with backports on Plasma 5.14.2.

I am able to browse the phone successfully by inputting the directory manually.
Comment 33 Laosom 2018-11-03 13:49:49 UTC
After upgrading to kdeconnect 1.3.2 same results for me.
I can also browse the phone folders by pasting /run/user/... to Dolphin,
but not by opening the phone object .

I also confirm to experience this on Neon 5.14.X , info details as wrote earlier. There is no update to the KDEconnect Android app and my phone runs an older Android  (4.x).
It would be nice to get a feedback from the develeopers if they can reproduce it or not.

Can you elaborate on this? It was working with an older version of kdeconnnect, but upgrading to 1.3.2 caused problems? Can you downgrade and verify?

I do not have problems on Fedora 28/29 Plasma 5.12.6/5.13.5. So no, I cannot reproduce this. None of us run Neon, as far as I am aware. I have not yet had time to install a Neon VM and test there.

Hello Simon,

No matter the kdeconnect version, it started to fail only on Neon from the 5.14.X updates. No issues on Arch or Kubuntu with Plasma 5.12 / 5.13 /5.14. What do you mean "none of us"  ? You mean kdeconnect developers :))) ? Thanks.

Neon 5.14 seems to be the common denominator here, which unfortunately comes with a huge number of variables, so it will not be easy to chase down unless someone takes serious ownership of it

Neon being the "techdemo" distro of KDE Plasma 5, and thought kdeconnect is integral part of it , it's strange to hear that and not a good promotion of Plasma . I hope someone will pick this up sooner or later. If I compare it with Kubuntu 18.10 with backports ppa the OS base is definitely older (Ubuntu 18.04 LTS) in NEON. I am going to check the other parts.

I don't think I quite see the point being made here. KDE Connect has a very small development team (depending on how you count, somewhere between 5 and 10, probably closer to 5). I would rather use the system I am most familiar with (dnf/yum/RedHat) and be able to focus more effort on work and hobbies. This does not detract from the usefulness or value of Neon, just that its goals do not align with mine.

One of KDE Connect's goals is to be distribution- and desktop-environment- independent, so I wouldn't describe it as being "integral" to Plasma 5 or Plasma 5 being integral to KDE Connect, even though we do integrate nicely with Plasma.
Comment 41 Andras 2018-11-03 23:13:30 UTC
(In reply to Simon from comment #40)
Then It's a great example then users shouldn't rely on and cling to specific open source projects by names and shouldn't be loyal and shouldn't expect loyalty.
I see some development makes its testing on more popular Distributions however as a not developer I assumed KDE project testing on KDE neon first as a matter of respect and if KDE neon itself wants to reach any level of popularity. If KDE Connect project is based on popularity so much then it should and I think it'll change its name sooner or later. Simon don't get me wrong, keep up the good work. Maybe I'll change my aspects and get other options that's all.

Thanks Simon for the explanation. I really thought Kdeconnect is a Plasma application an part of Plasma. The name of the product was the cause I think.
I respect your great work with this great app. 
I don't use Neon as my daily driver either, as the KDE team states it's not quite a distro . They needed a stable base (Ubuntu LTS) for the latest KDE software to be built on. The first minor versions of a new release is always full of bugs , but the last builds were OK and very fine for daily use.
The current version 5.14 is expecting 3 more bugfix releases in the upcoming months and compared to Kubuntu I can use more up-to-date KDE Software.
For example Debian Stretch has Plasma 5.8.9 ; Kubuntu 18.04 LTS has Plasma 5.12.6 LTS ; Kubuntu 18.10 has Plasma 5.13.5 and with backports enabled 5.14.2 , but the KDE Applications is still older (18.04) compared to NEON (18.08.2).
The interesting thing is Arch / Manjaro is also on the latest of everything and this bug does not exist there. 
Nathan Graham stated the following in his blog regarding 5.14 : 

https://pointieststick.wordpress.com/2018/10/14/this-week-in-usability-productivity-part-40/

"We apologize for these bugs and we’re working to get them fixed quickly!
One of the reasons why bugs like this squeak through is that we don’t have enough pre-release QA testers. You could be one of them, and next week, your name could be in this list! Just check out https://community.kde.org/Get_Involved, and find out how you can help be a part of something that really matters. You don’t have to already be a programmer. I wasn’t when I got started. Try it, you’ll like it! We don’t bite!"

It would be really nice if one you could test Neon VM and get in contact with the Neon team what's going on ;)
Many thanks.

The same for me with Android 7.0, Neon 5.14.2, kdeconnect 1.3.2.
I am neither able to browse the phone from /run/user/... neither in a terminal (I receive a permission error)  nor in Dolphin (where the error is that the protocol kdeconnect died)
Comment 44 Andras 2018-11-04 16:05:13 UTC
I made a several attempts and increasing max_user_watches at boot seems to be the most significant one. Although I'm not sure if this single step would help for some so let me know how is it work:
https://github.com/guard/guard/issues/229
http://blog.sorah.jp/2012/01/24/inotify-limitation
https://askubuntu.com/questions/154255/how-can-i-tell-if-i-am-out-of-inotify-watches
In short place this line into your /etc/sysctl.conf :
fs.inotify.max_user_watches=100000
Also even if it helps, I don't think this is the real solution, I see it as a workaround only.
Comment 45 Simon Redman 2018-11-04 18:29:28 UTC
Here is my diagnosis after a few hours with a Neon 5.14 VM:
- The issue described is reproducible on a fresh installation
- The issue described is not present on a build of the 1.3.2 branch on my Fedora system
- The issue is not 100% reproducible. Sometimes I could click on the phone shortcut in Dolphin and everything would just work as normal. I could not figure out how to reliably trigger this good state, but it would seem to work for several tries after starting to work, then eventually give up
- This happens with KDE Connect installed from a build from the master branch in git as well as installed from packages
- This happens with package version 1.3.0-0ubuntu1 as well as the latest available 1.3.2-0xneon+18.04+bionic+build7
- The behavior for `kioclient cat kdeconnect://<device id>` differs between my Neon VM and my main Fedora system:
  - When kdeconnectd is not connected, on Fedora kioclient5 immediately exits with a 0 return code. On Neon, it pauses for ~2 seconds then exits with "The process for the kdeconnect://<device id> protocol died unexpectedly" and a non-zero code (specifically, 1)
  - When kdeconnectd is connected, the behavior is apparently the same (nothing successful-looking is ever written to the console)

Most interestingly, nothing gets logged by kdeconnectd when the icon gets clicked in Neon. As in, no crash, nor failed connection. In Fedora, "stuff" happens (indicating the device is mounted, etc.)

This suggests that something in the pipeline between KIO and KDE Connect is the cause of the trouble.
Comment 46 Erik Duisters 2018-11-05 16:52:03 UTC
After playing around with a KDE Neon VM I noticed the following error in ~/.xsession-errors:

kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/qt5/plugins/kio_kdeconnect.so' from launcher.
kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/qt5/plugins/kio_kdeconnect.so'
QCoreApplication::arguments: Please instantiate the QApplication object first
QCoreApplication::applicationDirPath: Please instantiate the QApplication object first

KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name =  path =  pid = 2439
KCrash: Arguments: kdeinit5: PID 2439 terminated.

That got me looking at other KIO slaves (eg ftp) and apparently things have changed a bit:

Instead of a .properties file they now use a .json file to define the plugins metadata and embed that using a dummy class having Q_PLUGIN_METADATA(IID "xxx" FILE "xxx.json")

Then in the kdemain function they initialize a QCoreApplication object.

Last but not least I now had to move kio_kdeconnect.so to /usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/

Let me do some more test to see if it also works on my fedora system and I'll upload the patch to phabricator

Comment 48 Nicola Jelmorini 2018-11-05 19:00:55 UTC
This morning I have received an update for the KDE Connect app on my phone. Now I have the version 1.10 on the phone, and version 1.3.2 on my PC.
In the changelog on the phone, one of the items is:
"Fixed remote file browsing (needs desktop version 1.3.2!)"
But, I still have the issue. No way to browse the phone files with Dolphin.
Comment 49 Andras 2018-11-05 19:25:39 UTC
(In reply to VosaXalo from comment #48)
Yes, I saw it too and installed it with hope. I bet it was fix for remove file browsing maybe for many distribution even for OS from Rendmond but not for KDE neon. I just started to thinking about buying a new Windows licence if it gets more support even from Linux open sources.

Nice, I'm glad it seems to be solved, thanks for the hard work!
I noticed something tough and I hope not but if this issue remains somehow then may I highlight these two line from result above?:
---
kdeconnect.plugin.sftp: Starting process:  "sshfs kdeconnect@192.168.1.90:/ /run/user/1000/6745be67c0caf8bb -p 1739 -s -f -F /dev/null -o IdentityFile=/home/adam/.config/kdeconnect/privateKey.pem -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o HostKeyAlgorithms=+ssh-dss -o uid=1000 -o gid=1000 -o reconnect -o ServerAliveInterval=30 -o password_stdin"
--
kdeconnect.plugin.sftp: stdout: "Warning: Permanently added '[192.168.1.90]:1739' (RSA) to the list of known hosts.\r\n"
---
Technically speaking I know nothing about networking in deep but isn't KDEConnect asks for ssh-dss type algorithm and by the end the system try to give ssh-rsa?  I mean is it possible it's something with cryptographic algorithms compatibility that the system in KDE neon won't provide the legacy one?
Related to this, once I got this line for example:
---
kdeconnect.plugin.sftp: stdout: "Unable to negotiate with 192.168.0.0 port 1739: no matching host key type found. Their offer: ssh-rsa\r\n"
---
It's a long shot and maybe I'm speaking about nonsense but just in case I ask.
Comment 53 Andras 2018-11-06 02:13:34 UTC
You guys are awesome how fast the upgrades appeared in packages, thanks. I assume it was related to this bug also.
I try to solve this on two desktop pc with two phone(beta app on both).
I hope it's only for me and the main issue is solved. I still can't get Kdeconnect to work. My process was:

Upgrade was done well, I mean everything installed flawlessly, kdevplatform52-libs was removed.
Restart --> still won't work
Remove /var/tmp/kdecache-user /~.cache/kio /~.config/kdeconnect and remove data from kdeconnect app on phone
Restart --> still won't work

The issue is the same, I mean I get the very same messages except right after the upgrade I got some additional stuff implemented by you guys I think, such as:
kdeconnect.plugin.sftp: add to dolphin
I'd like to note also, I still get the same result I mentioned above:
kdeconnect.plugin.sftp: stdout: "Unable to negotiate with 192.168.0.0 port 1739: no matching host key type found. Their offer: ssh-rsa\r\n"

Sorry if this is overly obvious, but did you reboot after building and installing? I had to reboot to get my system / KIO to pick up the new change. Is your cmake configured for the correct install prefix?

I upgraded all components, but getting same error even after reboot

Comment 59 Laosom 2018-11-06 14:23:32 UTC
I have also upgraded my kdeconnect package to

kdeconnect:amd64 (1.3.2-0xneon+18.04+bionic+build7, 1.3.2-0xneon+18.04+bionic+build8)

and also the kdeconnect app to 1.10.
Cleaned up /home/.../.config/kdeconnect folder, reboot
Phone readded .
Same error during filebrowse in Dolphin :(
Comment 60 NiO 2018-11-06 14:35:07 UTC
Since I seem to be the only one this patch seemed to have helped, I thought I should mention I also built and installed the latest sshfs and libfuse3 from source at the suggestion of another user.  I don't personally understand the low level interactions between these packages and KDE Connect so I don't know if this is relevant at all, or if it will help anyone, but KDE Neon packages a very outdated version of sshfs from 2016.

Default package versions:

$ sshfs --version
SSHFS version 2.8
FUSE library version: 2.9.7
fusermount version: 2.9.7
using FUSE kernel interface version 7.19

My current version:

$ sshfs --version
SSHFS version 3.5.0
FUSE library version 3.1.1
using FUSE kernel interface version 7.26
fusermount3 version: 3.1.1

Do this at your own risk, it may have other implications on your system.  There might be a reason KDE Neon chose to provide old versions of these packages.

The only issue I'm currently having is I lose pairing after every reboot and have to re-pair my device every time I need to access it.  I've done so much mucking around with system components I may have screwed that up myself though.

Version 1.3.2-0xneon+18.04+bionic+build8 doesn't have these patches.
Patch added 2018-11-06 at 13:22:50
Package created 2018-11-05 at 22:54

Comment 62 Albert Vaca Cintora 2018-11-06 15:31:14 UTC
You should get 1.3.3 soon, which fixes the issue.

No need to apologize... I did reboot, but didn't build anything. 

I got an update for KdeConnect on my system, so I figured that was the one that fixed it - my bad. I'll wait it out.
Comment 64 Andras 2018-11-06 20:02:37 UTC
Ok, although it's closed I'd note, I think it's because the older 1.3 version of KDE Connect what KDE neon kept asks for dated ssh-dss type of cryptographic algorithm what is disabled by default on current OpenSSH.

It's highly NOT recommended but you can enable it by placing a line into /etc/ssh/ssh_conf. However you should make a copy previously:
sudo cp /etc/ssh/ssh_config /etc/ssh/ssh_config.factory-defaults
Then add the following to ssh_config file:
    PubkeyAcceptedKeyTypes +ssh-dss
Even if you can't wait and make this modification, you should undo it right after you got KDE Connect 1.4.

Correct me If I I'm wrong.
Comment 65 Andras 2018-11-06 20:09:58 UTC
(correction for comment #64)
I wanted to write "you should undo it right after you got KDE Connect 1.3.3" what allegedly fix this issue.
Comment 66 Andras 2018-11-07 19:07:44 UTC
First of all, I apologize for all my rude replies. Nevertheless I'd like to give a feedback, 1.3.3 version of KDE Connect just arrived on my two pc with KDE neon and it works awesome with my cellphones. Thank you so much guys, many thanks for all your hard work!
Comment 67 Nicola Jelmorini 2018-11-07 20:12:47 UTC
I can confirm too, that with version 1.3.3 of KDEConnect the issue is finally gone.
Thank you very much for the support, and the work done.
Comment 68 Vanush 2018-11-07 20:20:19 UTC
Everything works for me after update, thanks for a great work
Comment 69 NiO 2018-11-07 21:04:03 UTC
This was working when I compiled the patched version, but I'm getting a new error from kdeconnectd now

When trying to pair desktop to phone:
I get request on my phone and I accept, the KDE Connect gui refreshes and it just says (not paired)

When trying to pair phone to desktop:
I get an accept/reject dialog, I accept.  The following error occurs on kdeconnectd terminal output


In both cases, the phone completely fails to pair now.  Any ideas?
