Description of problem:
SELinux is preventing colord from 'read' accesses on the Datei /var/lib/flatpak/exports/share/mime/mime.cache.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

Wenn Sie erlauben wollen, dass colord  read Zugriff auf mime.cache file
Then sie müssen das Label auf /var/lib/flatpak/exports/share/mime/mime.cache ändern
Do
# semanage fcontext -a -t FILE_TYPE '/var/lib/flatpak/exports/share/mime/mime.cache'
wobei FILE_TYPE einer der folgenen Werte ist: NetworkManager_tmp_t, abrt_helper_exec_t, abrt_tmp_t, abrt_upload_watch_tmp_t, abrt_var_cache_t, abrt_var_run_t, admin_crontab_tmp_t, afs_cache_t,

Führen Sie danach Folgendes aus: 
restorecon -v '/var/lib/flatpak/exports/share/mime/mime.cache'


*****  Plugin catchall (17.1 confidence) suggests   **************************

Wenn Sie denken, dass es colord standardmäßig erlaubt sein sollte, read Zugriff auf mime.cache 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 'colord' --raw | audit2allow -M my-colord
# semodule -X 300 -i my-colord.pp
