Description of problem:
SELinux is preventing snap-confine from 'getattr' accesses on the chr_file /dev/uhid.

*****  Plugin catchall (100. confidence) suggests   **************************

Wenn Sie denken, dass es snap-confine standardmäßig erlaubt sein sollte, getattr Zugriff auf uhid chr_file zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'snap-confine' --raw | audit2allow -M my-snapconfine
# semodule -X 300 -i my-snapconfine.pp
