Installing Open-Xchange 7.8 on UCS when the master is on 4.3

OX is on the verge of releasing Version 7.10. That version will not be supported on (or packaged for) Debian 8 Jessie, but only on Debian 9 Stretch (and of course RedHat and SuSE). On the other hand, 7.8.x will not be supported on (or packaged for) Stretch.

The latest UCS version is 4.3 at the moment. This is based on Debian Stretch.

Therefore the current OX is not supported on UCS 4.3, but according to Open Xchange an  Univention, OX 7.8.4 on UCS 4.2 is supported in an environment with 4.3 servers.

So, when your UCS master is running 4.3, you can theoretically run OX on a 4.2 server. This works fine when you installed OX while the master is still on 4.2 or earlier.

In my case, my master was on 4.3. In order to install OX, I set up a server with UC 4.2 and joined it to the master. This already broke on installation but worked in a later step flawlessly.

Next, I started to install OX:

Oopsie. But consistent: univention-app list doesn’t show oxseforucs on the master, therefore there are no package sources and no packages. Fsck.

So let’s do this manually:

Now you can install OX on the 4.2 server.





Nur so als kleiner Reminder…
