Summary:

SELinux is preventing the ck-get-x11-serv from using potentially mislabeled
files (.Xauthority).

Detailed Description:

[SELinux is in permissive mode, the operation would have been denied but was
permitted due to permissive mode.]

SELinux has denied ck-get-x11-serv access to potentially mislabeled file(s)
(.Xauthority). This means that SELinux will not allow ck-get-x11-serv to use
these files. It is common for users to edit files in their home directory or tmp
directories and then move (mv) them to system directories. The problem is that
the files end up with the wrong file context which confined applications are not
allowed to access.

Allowing Access:

If you want ck-get-x11-serv to access this files, you need to relabel them using
restorecon -v '.Xauthority'. You might want to relabel the entire directory
using restorecon -R -v ''.
