OES 2015 to OES 2018 upgrade, Print Manager and Driver Store won't load

After upgrading from OES 2015 to OES 2018, neither the Print Manager or Driver Store will load.  The Apache error log (/var/log/apache2/error_log) points to a certificate issue.

Copy/paste the following string of commands into a terminal session:

/opt/novell/iprint/bin/post_update_fix;rcnovell-idsd start;rcnovell-ipsmd start

The underlying OS to OES 2018 contains changes on how it loads services.  When doing an upgrade from OES 2015 to OES 2018, those changes result in the Print Manager and Driver Store failing to load.

There is a section of the OES 2018 iPrint documentation which specifically addresses this issue:
