Description Peter Schiffer 2014-02-17 16:51:47 UTC
Description of problem:
This occured while the printer was automatically installing.
SELinux is preventing /usr/bin/python2.7 from 'read' accesses on the directory /root/.local/lib/python2.7/site-packages.

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

If you believe that python2.7 should be allowed read access on the site-packages directory 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:
# grep udev-add-printe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 3 Miroslav Grepl 2014-02-18 13:13:26 UTC
You would not see it in enforcing mode. Also cups-config python script should be fixed.
