For systems with Dell management software installed, yum updates are
broken because of an incompatibility in the libsmbios library (see below)

If I remove the python-smbios, I can "fix" the problem in that updates now 
work, but this breaks the Dell management software. If I try to reinstall
  python-smbios, I run into the same incompatibility problem.

Does anyone know how to fix or work around this problem?

Thanks
Eve

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