upgrade from 10.13.2 to 10.3.3 fails with redis:6.2.14

[jnweiger]

• run the 10.13.3 appliance in virtual box
• ssh into the system
• upgrade to the 10.13.3 app from the test-appcenter:

univention-install univention-appcenter-dev
univention-app dev-use-test-appcenter
univention-app list owncloud
univention-app upgrade owncloud

owncloud fails to start. volume mounts are not used any longer. An empty config.php gets created.

In 10.13.2 we had two symlinks, that get lost during the upgrade:

Root cause analysis:

• docker redis:6.2.14 does not start, it loops in restarting
• error handling is lacking. scripts just continue. Everything else we see is red herrings.

Downgrading to redis:6.4.7 fixes everything.

Now univention-app upgrade owncloud works.
