ANSWERED Fedora 26 - cannot launch AirVPN client

[marmoset 0]

Hello,

 

I recently upgraded to Fedora 26 (GNOME environment) and I'm encountering problems launching the AirVPN client. I've tried using versions 2.12.4 and 2.13.6 of the client but I get the same problem with both.

 

I did a little digging and found this forum post (https://airvpn.org/topic/20750-airvpn-not-working-with-fedora-25-wayland ) about a problem similar to mine, but it's about an earlier version of Fedora and the proposed solution doesn't solve my problem.

 

Basically the error message I get when I launch AirVPN in the terminal is this

I do have the package "xorg-x11" installed so the problem can't be the absence of an X Server. But I'm not an expert and I am completely out of ideas as to what could be wrong here. Any help would be appreciated.

 

Thanks in advance.

Hello,

 

check whether disabling Wayland helps:

Hello,

 

Thanks for the quick reply. I'd already tried that which is why I posted this in the first place. But then it occurred to me that I didn't restart my computer between the file edit and relaunching AirVPN the last time around. Now everything works fine, so it was the same problem and a shortsight on my part.

 

Thanks again and sorry for the inconvienience.
