Collabora CODE server installation not working and occ user issues


I have installed Nextcloud 20.0.0 on an Synology DS220j and it is basically working. I have multiple users, connected with Android and iOS devices and my main Computer (Win 10) is syncning everything fine.

Now I wanted to check out additinal apps and try if I can get the collabora CODE server up and running.
First I ran into a timeout issue, which I think I could solve, but still the installation leads into an error.

So I tried the manual installation with occ, but this also leads into errors, while I noticed that there doesn’t seem to exist the www-data user on an synology DSM station.

Has anybody some knowledge about that?

Kind Regards

Just for reference. The user on a Synology user needs to be “http” not www-data.
