Description of problem:
SELinux is preventing cupsd from 'getattr' accesses on the file /var/cache/cups/job.cache.O.

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

If you want to fix the label. 
/var/cache/cups/job.cache.O default label should be cupsd_rw_etc_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.
# /sbin/restorecon -v /var/cache/cups/job.cache.O

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

If you believe that cupsd should be allowed getattr access on the job.cache.O file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'cupsd' --raw | audit2allow -M my-cupsd
# semodule -X 300 -i my-cupsd.pp

Comment 1 Zdenek Pytela 2018-12-27 12:19:48 UTC

It looks like the file in the setroubleshoot report has incorrect label. The unlabeled_t label is displayed when a file was created in SELinux disabled state or when its actual label does not currently exist. Along with the restorecon plugin suggestion, you can fix the label with a single command:

  # /sbin/restorecon -v /var/cache/cups/job.cache.O

or relabel all filesystems:

  # fixfiles onboot

and reboot the system.

Closing as NOTABUG. Feel free to reopen the bugzilla if the issue persists.
