Mono-based app no longer starts on Tumbleweed

Hi guys, I have been using a VPN client called AIRVPN on occasion. After one of the most recent updates for Tumbleweed it will no longer start when I try to launch it from the shortcut. If I try to start it in terminal I get this error:

[FONT=monospace]sudo airvpn

I contacted the AIRVPN people but they appear to have no clue. There was a common bug with apps that use mono including this one where a file called libgdiplus.so wasn’t linked properly but that is not the problem. I uninstalled and reinstalled the mono packages including mono-complete but that had no effect. I THINK this may be a permissions problem but honestly I’m not sure. If anyone has any ideas, please let me know! (also it is worth noting that I get a different error when I use su and then run the program in terminal but I think they are unrelated. Regardless, the regular sudo command in terminal used to work with this app so that should not be the issue.)

But in case it does matter, here is the output I get when I run su and then the vpn client:

This may be the actual problem, I’m not sure.

Sorry for the spam of posts but disregard that second post about the su, that clearly is not the issue!

Looks like your stdout includes 2 issues…

The most serious is that it can’t open a display.

The other mysterious issue are all those <filename unknown>.
Is that really what is being returned and not something you’re doing to sanitize the output?

In any case, the display error is somewhat explanatory.
Someone has to run a debugger (MonoDevelop?) and inspect the values presented, and modify.

Are you sure AIRVPN people refused to look into this more deeply?
As a compiled application, this isn’t something the End User is typically expected to resolve.

You will need to explain to AIRVPN you are running on a bleeding edge distro which is expected to integrate new architecture soon to be seen in stable releases so it’s in their best interest to resolve now before it’s seen by many more.

Thank you for letting me know this! I am relieved to see that it is something I can’t really fix on my own, I have been trying for some time now. I copied and pasted your message to the AIRVPN support, I hope that’s cool :slight_smile:

Sure, anything I post is public and quotable without asking…
