It is a few weeks that my documentation doesn’t build anymore on GitHub, and I can’t get back to the problem.
The actions log just tells me that the line where I call makedocs returns the above error:
qt.qpa.xcb: could not connect to display
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: linuxfb, minimal, offscreen, vnc, xcb.
Aborted (core dumped)
connect: Connection refused
GKS: can't connect to GKS socket application

My package has nothing to do with graphics, except a few plots that are present in some tutorials I am trying to build. But these were created without problems before. Any hint on where to look ?
