Original GitHub issue: https://github.com/debauchee/barrier/issues/323

Hi I have installed to my main computer which runs with ubuntu 18.04(server), the barrier using build from source. And I have install barrier-kvm from ubuntu store in my laptop which runs with ubuntu 16.04(client). But I couldn't manage to connect the two pc's any ideas?
Client Log error message: failed connect to server,can't create socket :Permission denied
I've tried to install barrier by building from source in my laptop also but was crashing and not manage to connect either .

Also Is there a way to uninstall barrier from source properly?

I don't know right off, you could try make uninstall

create socket :Permission denied

Hrmm, never seen this issue with barrier, wonder if that's something specific to barrier-kvm from the ubuntu store. Did you install the snap?

@tassosblackg commented on GitHub (May 27, 2019):

make unistall doesn't work there is no such rule in makefile.

I've tried also barrier builded from source in

ubuntu16.04

but it didn't connect, and also was had some issues with its gui/

I don't think there is a difference between versions of ubuntu store and source the both are 2.2.0.

Is there a possibility to be because of firewall rules?

Maybe, but the permission denied error refers to a user permission. I don't have much experience troubleshooting unix sockets. My only guess is to stop all Barrier processes and remove all temporary Barrier temporary files with rm -f /tmp/Barrier*.

I find a way just to delete all the installed files :
sudo xargs rm < install_manifest.txt and then remove the whole dir

After that, I installed all using flatpak on both machines. It worked except a fingerprint issue on server that fixed by this https://github.com/debauchee/barrier/issues/231#issuecomment-456327061

I get a warning when opening barrier:

'System tray is unavailable, don't close window'

But it works after all.

forgot to mention that I had to customize my firewall, in case you don't have it enabled you'll be ok

That warning is GNOME specific and had yet to be fixed.
