Description Matthias Andree 2019-07-07 09:42:39 UTC
Description of problem:
SELinux is preventing pool-gsd-xsetti from 'map' accesses on the Verzeichnis /var/lib/gdm/.cache/fontconfig.

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

Wenn Sie denken, dass es pool-gsd-xsetti standardmäßig erlaubt sein sollte, map Zugriff auf fontconfig directory 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 'pool-gsd-xsetti' --raw | audit2allow -M my-poolgsdxsetti
# semodule -X 300 -i my-poolgsdxsetti.pp
