Description of problem:
SELinux is preventing snapd from 'execute_no_trans' accesses on the fichier /usr/libexec/snapd/snap-seccomp.

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

Si vous pensez que snapd devrait être autorisé à accéder execute_no_trans sur snap-seccomp file par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
autoriser cet accès pour le moment en exécutant :
# ausearch -c "snapd" --raw | audit2allow -M my-snapd
# semodule -X 300 -i my-snapd.pp
