Description William Brown 2015-06-08 21:30:07 UTC 
Description of problem:
Run dnf upgrade on F22 as a confined root user.
SELinux is preventing /usr/bin/python2.7 from using the 'transition' accesses on a process.

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

If you believe that python2.7 should be allowed transition access on processes labeled rpm_script_t 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 dnf /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
