Bug 417754

Thank you for reporting this issue. 

I noticed this error message also just recently. It is reported for example if no workgroups or domains were found. I will fix it shortly.

Stop Smb4K from reporting an error if the query for domains and workgroups fails.

Improve fix: Only exit silently when the query for domains and workgroups failed. So, an
error will still be reported when another URL does not exist.

@Alexander - I am still seeing this message ("The URL does not exist") upon my Fedora 32 system which uses smb4k-3.0.6-1.fc32.x86_64. From looking at https://invent.kde.org/network/smb4k/-/blob/master/ChangeLog I thought it was resolved. I think it would be useful to be able to get more logging/debugging (e.g. which URL) as I am not sure how to diagnose it further.

Thank you for reporting this. Indeed, this problem should be fixed. I will investigate this further. 

To be able to reproduce this, can you please tell me, if you have a firewall installed and if your computer is part of a Windows domain or workgroup?

Hi. I do have a firewall (as part of the default F32 install) and I am not part of any workgroup/domain. Just in case it could affect it, I do have a kerberos configuration as part of my work setup. To verify whether the firewall affects it, I did 'systemctl stop firewalld' and then restarted smb4k and I get the same error. If there is anyway of retrieving more helpful logs for you, I'd be happy to.

i get the same issue at Manjaro KDE v20.1 RC3
smb4k 3.0.6

i run the manjaro in a vmware on Windows 10 Host
i opened windows  sharing and the windows file wall

when i start smb4k, it prompts two message: 1. said theres samba.conf missing, 2. is the URL does not exist issue
then refresh network in the smb4k, it will say 'url does not exist issue' again

Thank you for the additional information and please excuse my late response. First I was very busy at work and later I was on vacation.

I am not quite sure if the Kerberos setup might lead to the error, because all the authentication stuff is done by libsmbclient.  

The fact that you use Kerberos indicates that you are in a Windows domain. Is that correct?

The first warning message is prompted, because Smb4K is trying to read the smb.conf file and cannot find it. I am thinking about removing that message. The second message is prompted, because something went wrong with the initial browsing. Are you in a Windows domain or do you have a workgroup setup?

No problem :-)

No, sorry I'm not. The kerberos is used as part of authentication to various (non-windows) services at my work. Template file is https://github.com/rnc/nicks-shell/blob/master/ansible-linux/templates/krb5.conf.j2
 

I think its happening on initial startup when it searches for "workgroups and domains". I can reproduce it on demand by manually running Network/"Scan Network"

I removed the function that reads the smb.conf file, so the first warning message will not appear anymore with Smb4K master.

Unfortunately, I was not able to reproduce the second problem yet. It seems that my setup is different from the one you use. Do you also use Kerberos?

Thank you for reporting this issue.

Have you tried the approach mentioned in the handbook under "Special Remarks": https://docs.kde.org/stable5/en/extragear-network/smb4k/special_remarks.html#special_remarks_problems_browsing_samba_47 ?

Does the scanning work when you apply the changes to the smb.conf file?

I have tried with

client max protocol = NT1

in the /etc/samba/smb.conf but it makes no difference. I see in the journal

Nov 26 13:13:34 atlantis smb4k[3402747]: Neither size nor group specified!
Nov 26 13:13:34 atlantis krunner[3402747]: lp_load_ex: Max protocol NT1 is less than min protocol SMB2_02.

Link no longer valid.

It has moved:

https://docs.kde.org/stable5/en/smb4k/smb4k/special_remarks.html

however I don't see #special_remarks_problems_browsing_samba_47 there.

Which version of Smb4K are you using? With Smb4K 3.1.0 or 3.0.7 this should not happen no more.

The handbook was updated to version 3.1.0 recently. To view the handbook for your installed version of Smb4K, plase press the F1 key.

Thanks. I'll do an upgrade and try again. Thanks for all your work :-)

Since this bug has already been fixed, I close this report.
