Nextcloud seems to be stuck in restart loop after upgrading to Cloudron v8.0.3

[nottheend]

The Nextcloud app seems to be caught in an infinite restart loop since few hours.
Checking the logs, I can see one outstanding recurring log entry in red:

Aug 06 18:17:45 <30>1 2024-08-06T16:17:45Z  - Command "upgrade" is not defined.

This is "the whole loop"in truncated logs, execpt the App updates:

I was able to solve the issue by stopping the nextcloud app and afterwards rebooting the Cloudron Server. After the Cloudron Server came up again, I waited for a grace period and started the Nextcloud App afterwards again.

It should be mentioned that the reboot of the server took exceptionally long, more than 45 min. I didn't investigate the root cause.

This topic can be marked as solved.

Such a long reboot time is quite unusual indeed. Maybe your server provider has some infra issues?
