DBUA Upgrade Question

The problem that I had with the last attempt was that the timezone upgrade in the PDBs failed. I told it to ignore that error and finish. First, I don't understand why it failed. Second, how can I fix it and what do I have to do different to make it work?

Here's the contents of the log file for the timezone upgrade in the PDBs:

catcon: ALL catcon-related output will be written to [/oracle/app/cfgtoollogs/dbua/upgrade2018-07-25_12-59-49-PM/DBAZTECT/PDBSUpgradeTimezone_catcon_31240.lst]
