I was running owncloud successfully for quite a while now on my private UCS server. Today I updated UCS to 5.0-4 and after having done that I also updated the owncloud server from something 9 to the most recent 10.12.1.
After that I noticed that the server did not accept the additional URLs as trusted which I had added to /config/config.php at earlier versions.
univention-app shell owncloud to enter the container shell and found out that the domains were gone, indeed. So I made a backup copy of /config/config.php and added the URLs/domains as before. However, this did not change anything. So I changed the order of the domains in config.php to find out whether this makes any difference. Yes it did, this way the local domain did not work anymore either. So I put the original config.php in place again → no change. The local domain did not work. Finally I even uninstalled owncloud and reinstalled it. Again, no access by local domain anymore. Now I am stuck.
Does anybody have any idea about that ? Or should I rather install nextcloud instead ? Any ideas are welcome …
