Error upgrading OTRS 6 patch22

[daveybops]

Hello everybody!

I have a stand-alone tower with OTRS 6 installed with ITSM on Ubuntu Server 18.04 It hardly has any data yet, except a couple of customer details in ITSM. I've attempted an upgrade to patch 22 using the directions described here https://doc.otrs.com/doc/manual/admin/6 ... ating.html and it's all unravelled. I'm prompted with the login screen and after I log in, I get 500 Internal Server Error and apache error logs show me this

The pertinent line to be entering in to Google seems to be Can't locate Kernel/System/DynamicField/ObjectType/ITSMChange.pm but I've not found much to help me fix.

I have a clone of the whole OS before upgrade, so I can try the upgrade again with a suggested route to avoid failure, or fix the failed upgrade, either way is good. Pointers, are very very much appreciated

Found fix with assitance of the Facebook OTRS group.

It had failed to update modules (ITSM)

I found that I could install the bundle if I downloaded (wget) from https://ftp.otrs.org/pub/otrs/itsm/bund ... 6.0.22.opm and command sudo -u otrs /opt/otrs/bin/otrs.Console.pl Admin::Package::Upgrade /path.to/downloaded_file.opm

I haven't yet identified how to change the URL that the system uses to find updates to modules. But sure I can with a bit more searching.
