Vorta doesn't work when installed from source #1699

Closed ratchek closed 1 year ago

Description

After installing vorta from source according to the Contributing Guidelines , when I try to run vorta from the terminal in the python virtual environment, I get the following error:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: wayland, wayland-egl, xcb, offscreen, vnc, linuxfb, eglfs, minimalegl, vkkhrdisplay, minimal.

Aborted (core dumped)

When I try to run the tests, I get the following:

People here installed libxcb and were able to fix this error, have you tried this?

Yeah, I tried that and it didn't work.

m3nu commented 1 year ago

Have you tried installing libegl1

I just fixed the same thing for our Github Actions process. https://github.com/borgbase/vorta/pull/1685/commits/50d2db30d1f6afae8964682ef5b53f7819ff951f

m3nu commented 1 year ago

Else you can copy the dependencies from GH Actions. They will definitely work on Ubuntu. https://github.com/borgbase/vorta/blob/master/.github/workflows/test.yml#L65

Might be worth adding this in the docs. I wonder if PyQt has some docs on this.

Installing libegl1 didn't work, but installing the dependencies from GH Actions did. Thanks!
