Upgrade step drop_apache_foreman_group failed.
On latest nightly, when running
foreman-installer --upgrade I get:
Upgrade Step: drop_apache_foreman_group... Removing user apache from group foreman gpasswd: user 'apache' is not a member of 'foreman' gpasswd -d apache foreman failed! Check the output for error! Upgrade step drop_apache_foreman_group failed. Check logs for more information.
This step was added in https://github.com/Katello/katello-installer/commit/7e2b81d6e12ecf9e0c4b1ebda0895001a2a9d211 and seems not to work when the Apache user isn't member of the Foreman group to begin with.
