Description Martin Wolf 2018-04-16 12:50:00 UTC
Description of problem:
SELinux is preventing snapd from 'map' accesses on the Datei /var/cache/snapd/commands.db.

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

If you believe that snapd should be allowed map access on the commands.db file by default.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
allow this access for now by executing:
# ausearch -c 'snapd' --raw | audit2allow -M my-snapd
# semodule -X 300 -i my-snapd.pp
