Topic: yum update error: Cannot find a valid baseurl for repo: base

[Jean-Philippe Pialasse]

I did a fresh install of 9.2 a few days ago. Tried applying fix and had the same error as ldkeen.
 
  "Error: Package: smeserver-yum-2.4.0-30.el6.sme.noarch (smeupdates)
           Requires: yum-plugin-post-transaction-actions"

added to smeupdates so it should not block anymore
