silent upgrade 8.0.3 to 9.0 seems stuck on Applying the 'utf8mb4_general_ci' collation

I am trying to upgrade my development environment from 8.0.3 to 9.0.0 but it appears to get stuck on


 [Upgrader] - Applying the 'utf8mb4_general_ci' collation to the database and all existing tables


I did not have this problem with the developer release but I was testing on a copy of the instance with little or no data, I am not sure if that makes a difference.

I ran 

SHOW COLLATION WHERE Charset='utf8mb4'

on my db and utf8mb4_general_ci is the default so I'm not sure why it's not progressing.



Any suggestions to get things moving along or where to look for problems?
