Description Thiago Macieira 2020-07-15 17:35:20 UTC

SUMMARY
In Akonadiconsole, the IMAP agent may display "Connection Established" but have no active IP socket open.

STEPS TO REPRODUCE
1. Disable Qt bearer plugins: chmod 0 /usr/lib64/qt5/plugins/bearer
2. Restart IMAP agent

OBSERVED RESULT
"Connection Established" is shown, never changes, but there's no outgoing socket open.

EXPECTED RESULT
Either there's an active socket connection or the state is something different.

SOFTWARE/OS VERSIONS
openSUSE Tumbleweed 20200701
Qt: 5.15.0
KDE Frameworks: 5.71.0
kf5-config: 1.0

As you can see, there's no "inet" file descriptor.

Comment 1 Arek Guzinski 2020-11-29 19:58:17 UTC

Same problem here with 5.15.3 on KDE neon (20.04 based)

in akonadiconsole:
Akonadi Server Self-Test shows no errors.
IMAP agent:
Status: Offline, Idle
Status Message: Connection established

lsof -n -p `pgrep -f akonadi_imap_resource_1` | grep -v 'mem'
shows no IP file descriptors (this is on my main computer - it does show them on my laptop, where akonadi is working fine)

But: bearer plugins are enabled (or am i missing one?)
# ls -la /usr/lib/x86_64-linux-gnu/qt5/plugins/bearer
total 612
drwxr-xr-x  2 root root   4096 Nov 20 10:29 .
drwxr-xr-x 73 root root  53248 Nov 28 23:14 ..
-rw-r--r--  1 root root 233536 Nov 10 18:12 libqconnmanbearer.so
-rw-r--r--  1 root root  81224 Nov 10 18:12 libqgenericbearer.so
-rw-r--r--  1 root root 254096 Nov 10 18:12 libqnmbearer.so

There are no helpful messeges of any kind - clicking on "Check Mail" in kmail does absolutely nothing.

I also tried resetting akonadi by following the steps at https://wiki.ubuntuusers.de/Akonadi/#Akonadi-zuruecksetzen (in german) and reconfiguring the IMAP agent. This did *not* fix the problem...

So currently I can't check my mails on my main computer. Help!

Comment 2 whatifgodwasoneofus 2025-09-29 15:54:29 UTC

I have the exact same issue here, after 5 years and several versions later. My system is:

Akonadi Console: 6.5.1 (25.08.1)
KDE Frameworks: 6.18.0
Qt: Using 6.9.2 and built against 6.9.2
Manjaro Linux (Wayland)
Build ABI: x86_64-little_endian-lp64
Kernel: linux 6.17.0-0-MANJARO

Comment 3 whatifgodwasoneofus 2025-09-29 18:30:34 UTC

(In reply to whatifgodwasoneofus from comment #2)

I fixed it. It was the connectivity check of NetworkManager - see this old entry:
https://www.reddit.com/r/kde/comments/uulpcv/i_get_limited_connectivity_even_though_my/

In /usr/lib/NetworkManager/conf.d/20-connectivity.conf I have:
----
[connectivity]
uri=http://ping.manjaro.org/check_network_status.txt
----

but it seems not to be responding, therefore NetWorkmanager thinks I have “limited connectivity” and akonadi (can’t figure out why) stays offline.

I solved by creating a NetworkManager config file that disables that check:

/etc/NetworkManager/conf.d/disable-connectivity-check.conf:
----
[connectivity]
enabled=false
----

and then restarted NetworkManager. Now IMAP agents do stay online.

So, the reason was that the "ping URL" was unresponsive, but honestly I could not relate any role of NetworkManager with this...

Comment 4 Thiago Macieira 2025-09-29 20:42:41 UTC

You fixed your problem, but not this problem. It might be related that Akonadi gets confused by the online status of VPN going up and down, and suspend/resume in different locations, but NM isn't confused in my case. So there may be another problem elsewhere.
