Running foreman-installer after updating the packages to katello 3.16 or 3.17 from 3.15 using their respective foreman 2.1 or 2.2 versions fail where the installer is doing the foreman-maintain packages locked check.
Exact issue is described in Bug #31135: foreman-maintain package lock check indicates false failure - Installer - Foreman and was fixed in foreman 2.3
Release notes or upgrade doco do not mention any action a customer can take to upgrade from 3.15, and doco specifically say upgrades of up to 2 versions only is supported.
So how would one upgrade to say 3.17 from 3.15, if the fix was not backported to 3.16 or 3.17?
Running foreman-installer works without an error during upgrade to katello 3.16 or 3.17 from 3.15.
