im testing at the moment the dockerized Master of UCS. On docker hub itself is a 4.4.4 version but it is not possible to upgrade these to 5.x.
Is there any procedure how to come to a current version?
I have already tried this: UCS 4.x apt key expired, no package installation,update, app installation is possible
After that i can upgrade to 5.x but my docker will be killed and not longer be startable. Any idea what i can do?
