Description Stephen Finucane 2019-05-08 09:24:11 UTC

Description of problem:
SELinux is preventing lightdm from 'rename' accesses on the file .xsession-errors.

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

If you believe that lightdm should be allowed rename access on the .xsession-errors 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 'lightdm' --raw | audit2allow -M my-lightdm
# semodule -X 300 -i my-lightdm.pp
