Hello folks,
Recently we observed broken yum one of our servers. yum commands doesn't seem to work specifically with root user of sudo privileges.
if I run it with sudo privileges or root user get given below error.
Code:
$ sudo yum repolist
Loaded plugins: fastestmirror, rhnplugin
Traceback (most recent call last):

same is running without sudo.

To fix this I've tried to reinstalling rpms for yum and python-libs
As dirty fix tried manually copying all the folders associated with files listed in error from working centos 7 machine having same version of packages.
same version of packages are working on other server.
How to reproduce :- don't know
kindly let me know if you are able to see further posiblities of debugging this and finding root cause for this.
I am trying to see if there is any issue with root account environment or any issue with sudo environment.
kindly guide me in finding root cause for this problem.
Regards
