SUMMARY When running NetworkManager 1.44 and plasma-nm, and restarting NetworkManager (e.g. with `systemctl restart NetworkManager`), the plasma-nm applet enters a weird state where it always shows "No connections found", despite NM operating properly in the background. Restarting Plasma or the applet (if loaded separately) fixes it until the next NM restart. Reported in NixOS: https://github.com/NixOS/nixpkgs/pull/263985 Also reported in Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1053707 Also similar issues reported in Arch: https://www.reddit.com/r/archlinux/comments/16in04o/plasma_nm_applet_does_not_show_any_networks_and/ STEPS TO REPRODUCE 1. Use NetworkManager 1.44 2. `systemctl restart NetworkManager` OBSERVED RESULT Applet shows "No connections found" EXPECTED RESULT Applet shows connections properly SOFTWARE/OS VERSIONS Linux/KDE Plasma: NixOS unstable KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.110 Qt Version: 5.11 + KDE patchsets ADDITIONAL INFORMATION This used to work fine with NM 1.42.x, so something must have changed in between 1.42.x and 1.44.0 that causes this behavior.
Thanks! There are other reports about this being broken, but that it's related to the NetworkManager version is new and very useful information *** This bug has been marked as a duplicate of bug 471870 ***
I am actually not entirely sure this is the same bug - 471870 mentions the applet disappearing entirely, while at least in my case it is still there, just not listing connections.
There seem to be different symptoms for different people. For me the applet is there with no connections. They may or may not have the same root cause, we'll see after investigating
