I am new to the forum, so bare with me.
Problem: after recent univention-upgrade, OwnCloud stopped working on my private/test server.
Front-end: Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Latest version: 10.3.2
Docker container: running.
Troubleshooting (so far):
univention-app register OK
univention-app remove FAILS w/can’t backup data
univention-app install FAILS w/“it’s already installed”
univention-app upgrade FAILS w/same error as before
Notes: there’s something bizarre/consistent about each process. It tries to backup the previous container data, but fails.
Image upgrade script (pre) failed Storing data for 4.3/owncloud=10.2.1-1 failed Could not backup container! Aborting... Some networks were defined but are not used by any service: appcenter_net Starting redis ... Starting owncloud ...
Since this is a test environment, I would be okay to simply purge the container, unregister the app and reinstall, but if there’s more appropriate fix, I’ll take that instead.
I am sure I’ll be running into this in my production environments and it would be nice to know the proper way to handle it.
