Hello people, I'm using Ubuntu 22.04 LTS default installation fresh with almost zero packages extra installed, I tried installing calibre using the download command from the website and the error

Code:

Could not load the Qt platform plugin xcb

followed this link and installing some packages reccomended it solved that message but calibre still doesn't work, I've tried what here appear the problem is that message appear if you run in from the terminal:

Code:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

and the most important if that I try to use the book viewer it crashes and says that Qt WebEngine Render has closed and the terminal shows this:

Code:

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
The Qt WebEngine Render process crashed with termination type: 2 and exit code: 159
Restarting Qt WebEngine
The Qt WebEngine Render process crashed with termination type: 2 and exit code: 159
