    There was a problem importing one of the Python modules
    required to run yum. The error leading to this problem was:
  
       libelf.so.1: 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, Aug  7 2019, 00:51:29)
    [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]
  
    If you cannot solve this problem yourself, please go to
    the yum faq at:
