Pulp3 migration failed (Foreman 2.2/Katello 3.17)

Problem: After upgrading my Foreman server from 2.0 -> 2.1 -> 2.2. I wanted to try the Pulp3 migration. It seems to fail with the following error, the output below is all terminal output from all steps in the manual:

[root@foreman ~]# chmod -R g+rwX /var/lib/pulp/content
[root@foreman ~]# find /var/lib/pulp/content -type d -perm -g-s -exec sudo chmod g+s {} \;
[root@foreman ~]# chgrp -R pulp /var/lib/pulp/content
[root@foreman ~]# foreman-maintain content prepare

The following steps ended up in failing state:

  [content-prepare]

Resolve the failed steps and rerun
the command. In case the failures are false positives,
use --whitelist="content-prepare"


[root@foreman ~]# 

As mentioned, this server was installed with Foreman 2.0 / Katello 3.15 and subsequently updated (back to back with reboots)

Expected outcome:
Content migration tool being happy
