Description Martin Stransky 2020-03-04 11:02:20 UTC
Description of problem:

SELinux is preventing /usr/lib/systemd/systemd-journald from read access on the lnk_file invocation:gnome-launched-firefox.desktop-13670.scope.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
invocation:gnome-launched-firefox.desktop-13670.scope default label should be session_dbusd_tmp_t.
Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly.
Do
# /sbin/restorecon -v invocation:gnome-launched-firefox.desktop-13670.scope

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that systemd-journald should be allowed read access on the invocation:gnome-launched-firefox.desktop-13670.scope lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd-journal' --raw | audit2allow -M my-systemdjournal
# semodule -X 300 -i my-systemdjournal.pp
