# yum update

There was a problem importing one of the Python modules

required to run yum. The error leading to this problem was:

   No module named yum

Please install a package which provides this module, or

verify that the module is installed correctly.

It's possible that the above module doesn't match the

current version of Python, which is:

2.7.11 (default, May 13 2016, 18:00:58)

[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)]
