Python update

Hello, I am running FreePBX 13.0.192.18 and trying to run some updates (the end goal being updating Python to 2.7). However all yum update, even after trying solutions from google, end up with this pair of messages.

Error: Package: asterisk13-core-13.17.1-1.shmz65.1.179.x86_64 (@pbx)

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I would appreciate any advice that would let me fix or bypass this in order to have Python running. Thanks in advance.
