Cannot update CentOS 7 Python 2.7.5-34.el7 to 2.7.5-38.el7_2
 

Hey guys

I just wanted to apply the Python update released just yesterday August 18.
Unfortunately it fails at the dependencies, see below.
The server is an up to date CentOS 7 that's used as a Zarafa 7.2.1 mail server.
I don't really think that my issue is server specific, which is why I didn't place my question in the server forum.

Any hint is greatly appreciated :-)

EDIT:
I figured that under /bin I do have 2 links to python2.7 folder. Maybe the Zarafa mail server installation does indeed interfere here...

/bin
lrwxrwxrwx. 1 root root 7 Feb 24 21:37 python -> python2
lrwxrwxrwx. 1 root root 9 Feb 24 21:37 python2 -> python2.7
-rwxr-xr-x. 1 root root 7136 Nov 20 2015 python2.7

Cheers
Juri

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

Does /bin/python exist?
Maybe reinstall python first

Nope, there is only a link python -> python2 and another link python2 -> python2.7. The real python package is under /bin/python2.7
I am somewhat reluctant to reinstall python, because I think that this python version linking is there for a reason...
Since I do have the necessary python-tlslite package installed, just not under /bin/python, but a link pointing at it, is there a way to instruct yum to look elsewhere for the dependency?

I finally solved it. It was indeed the Zarafa installation causing the issue. I removed the failing dependency python-tlslite and it's 3 dependencies, ran yum update to update python and reinstalled the just removed 4 packages. All fine now :-)
