Network manager on KDE: can't configure network #56410

Closed tobiasBora closed 5 years ago

tobiasBora commented 5 years ago

Issue description

After installing Network manager on KDE, I cannot configure the network/add vpn/...: nothing happens when I click on the button "Configure network".

Steps to reproduce

Install KDE plasma and network manager:

services.xserver.desktopManager.plasma5.enable = true;
networking.hostName = "myhostname"; # Define your hostname.
networking.hostId = "abcdef01";
# Enable network manager
networking.networkmanager.enable = true;
users.extraUsers.myuser.extraGroups = ["wheel" "networkmanager"];

and install it:

sudo nix-channel --update && sudo nixos-rebuild switch

Finally, reboot, check that your user belongs to the networkmanager group:

$ groups
users wheel networkmanager

and click on the network manager icon in the trailbar > button "configure the network" (translated). Nothing happens:

Is there anything in the journal?

So basically, both NetworkManager-wait-online.service and NetworkManager-dispatcher.service are dead:

After some search I found an explicit error running sudo journalctl -f:

Impossible de trouver le module « kcm_networkmanagement.desktop » Veuillez saisir « kcmshell5 --list » pour obtenir la liste de tous les modules.

which translates into

Could not find the module « kcm_networkmanagement.desktop » Please type « kcmshell5 --list » to get the full list of modules.

After running kbuildsycoca5 (both in root and user), I can see that this appears in the list when I run kcmshell5 --list:

kcm_networkmanagement      - Modifier vos connexions réseau

However, I still have the error even after logout/login...

tobiasBora commented 5 years ago

It also appears that typing

kcmshell5 kcm_networkmanagement

opens the menu! So no idea what is doing the applet... Maybe they call " kcm_networkmanagement.desktop" instead of "kcm_networkmanagement"?

One more update: from a fresh new user, it works...

tobiasBora commented 5 years ago

So I don't know what happened. I copied .local and .config to a backup .local_old and .config_old. Then I moved the folders from the old user: it worked. Then I removed .local/.config, and replaced back .local_old and .config_old to their original names... And it was working, even with the old conf ! Mystery... but my problem is solved. Guess we can close the issue?

@tobiasBora Yeah, sounds like you can close. Glad to hear your issue is resolved.
