There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   libsmime3.so: cannot open shared object file: No such file or directory

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:
2.7.5 (default, May 30 2023, 03:38:55) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
