Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
