Settings will not open/Gui unresponsive

[lolman9998]

Just installed and the ui doesn't seem to be working. Have tried rebooting, and, after looking at other issues installing libsecret. CLI Output -

eovpn
cannot import openvpn3

I can confirm openvpn is installed. More info - Arch Linux (Just reinstalled a couple days ago, fresh) Kde wayland Installed from AUR via yay

I can provide more info if needed. Thanks!

[jkotra]

did you install openvpn plugin for NetworkManager?

yay -S networkmanager-openvpn

[lolman9998]

yes, i have it installed. reinstalled for good measure, still nothing.

[jkotra]

looks like i didn't update AUR with bug fix point release. Pushed now. please update @lolman9998.

[lolman9998]

Issue still occurs. Heres another log in case something changed.

Should be all of it. Lemme know if anything seems off so I can fix it.

[lolman9998]

packages.txt Found out it wasn't finding all of them, heres a more complete list

[jkotra]

I was too busy IRL to setup and test.. might take a while. Apologies.

I tried installing eovpn directly from AUR with yay -S eovpn and it worked right correctly.

https://github.com/jkotra/eOVPN/blob/5713cf1044b2f59f73b27f7af8897f91e307c2bd/subprojects/networkmanager/eovpn_nm.c#L387-L393

My guess is that nm_client_get_version is returning null for reasons unknown.

If you would like to dig deeper yourself, take a look at eovpn_nm.c. It can be compiled as standalone single filw and you can find building instructions with GCC at top comment. (un-comment the main() at bottom)

[Pijuten]

same issue

[Pijuten]

same issue

For me it works on kde-plasma, but on i3wm I have the issue

[valerii15298]

I had the same problem and found a solution. You need NetworkManager to be installed and running. If you do not have it - install it. If it is not enabled or not running just do:

sudo systemctl enable NetworkManager.service
sudo systemctl start NetworkManager.service

This should fix the problem
