Description Justin Sherrill 2021-01-14 16:12:26 UTC
Description of problem:

Seen on both a user database and set of repos synced by a pulp developer.

During the migration with some data (unclear exactly what), you can get:

Comment 8 Lai 2021-03-16 17:40:13 UTC
There's no concrete way of reproducing the issue though I have encounter this in my migration with customer data before in python3-pulp-2to3-migration-0.6.0.  I have retested this with python3-pulp-2to3-migration-0.9.1-1.el7pc.noarch with customer data and all valid data migrated successfully.

And I have also verified that the code is in the system that I test it on.

Marking this as verified on 6.9.0_017.
