SUMMARY This is a clean archlinux installation, relevant installed packages: plasma-meta, sddm, kwallet-pam, plasma-wayland-session. After the first start, attempting to store the password for any wifi network fails with a "no agents were available for this request" error. The steps at https://techbase.kde.org/Projects/Solid/Plasma-nm suggest first checking if the plasma-nm kded module is running. That does not seem to be the case (the provided script returns "not running") and a run of qdbus does not provide anything looking like a `org.kde.plasmanetworkmanagement` line (which I get on another, older installation). I initially suspected something going wrong with kwallet (so I did re-create the wallet a few times, with either blank passwords or setting the password the same as the login password) but that had no effect. I suspect now for some other reason the kded module is not starting. Connection using nmcli works, but does not store the password in Kwallet (it gets stored in cleartext in the connection file at `/etc/NetworkManager/system-connections` instead). STEPS TO REPRODUCE 1. Start with a clean install (I tried a couple of times already) 2. Login (wayland session, but it looks the same on X11) 3. Try to connect to a password-protected wifi network from the applet 4. Connection fails, at any following attempt to connect or manage that network a message appears stating that "no agents were available for this request"; password is not saved; connection is not achieved OBSERVED RESULT The networkmanager cannot connect to password-protected networks. EXPECTED RESULT The networkmanager successfully connects to networks SOFTWARE/OS VERSIONS Linux: 5.15.90-1-lts KDE Plasma Version: 5.26.5 KDE Frameworks Version: 5.102.0 Qt Version: 5.15.8 Networkmanager Version: 1.40.12 ADDITIONAL INFORMATION Log for the latest run of NetworkManager, in case it might be useful... ``` Jan 29 22:22:47 Hostname NetworkManager[3295]: <info> [1675027367.1295] NetworkManager (version 1.40.12-1) is starting...

If you run: qdbus org.kde.kded5 do you see /modules/networkmanagement
No, I get ``` Error: org.freedesktop.DBus.Error.NoReply Message recipient disconnected from message bus without replying ``` not sure if it's related or another issue entirely :/
ok, so kded isn't running which is what hosts the agent. kded is a collection of multiple small applications for a range of background services. This probably means something is crashing kded, probably completely unrelated to networking. Please look for coredumps for kded5.
Thank you very much for your fast replies and sorry in advance for the silly question: (In reply to David Edmundson from comment #3) > This probably means something is crashing kded, probably completely > unrelated to networking. Please look for coredumps for kded5. Where would I find those? It looks like kded5 is not being run as a systemd unit (system or user) and there are no obvious errors showing up (searches for kded5 coredumps mention bad crashes of the entire desktop environment with the dump in clear sight, in my case everything else seems to be working fine).
So, I went on with the installation (mostly apparently unrelated stuff like firewall, backup, graphics drivers etc) and at some point I noticed that kded5 was running (qdbus org.kde.kded5 now gives a list of modules). Networkmanager passwords are now stored properly in Kwallett. I still wonder what the issue was and I'll report again if I ever figure it out, but for the time being I think the ticket can be closed. Thank you very much for the support!
