that refer to this problem, apparently after I got the last amdgpu driver from Ubuntu 21.04, some snaps no longer (or better, their GUIs don’t show, there is no actual crash of the process).
I did NOT install any external drivers, this is a fresh install of Ubuntu 21.04.
Say that some people saying that it is due to libdrm missing in the confinement and others said it is missing a OpenCL config.
Where can I report this problem? maybe someone here can answer Tobias question in Snappy.
The deb packages of libreoffice and thunderbird work great, but the snaps not.
This definitely deserves a bug report, it should be possible to create one by following the “Create bug report” link in the bottom of the launchpad question.
One thing that could help in figuring out what is wrong is the security log. You could run
journalctl -t audit -f
in one terminal, then start one of the affected applications, and in the terminal you might see some line containing the DENIED word. Those lines would be most helpful, but in any case it’s better to attach the full output to the bug report.
