Fix damaged nextcloud installation

[lifeboy]

(daftness alert)

I tried to mount a 2nd disk volume at /home/user-data/owncloud and assumed all would be fine...

Of course I copied to content of the original /home/user-data/owncloud first and then copied it back, but nextcloud says a error has occured.

Running the nextcloud.sh doesn't help, it complains about many things. Also tried running mailinabox again, but no joy.

How can I reinstall nextcloud without losing the rest of the configured services and email?

I tried running the script again...

Upgrading to Nextcloud version 24.0.6

Nextcloud is not installed - only a limited number of commands are available
                                     
  Command "upgrade" is not defined.  

If I could reinstall nextcloud, the upgrade command may work... How can I do that?

Ok, we got this to work again. Reading the installation script provided clues, so in the end, with the correct ownership of directories and files in /home/user-data/owncloud, it was responding again.

Strangely enough: We got a message saying there's a setting in config.php that is config_is_read_only = true. It stopped the upgrade from happening. So I changed that in the script (which creates this setting) and it upgraded properly it seems.

Why is that there?

There were a few issues being reported for a while, namely: https://github.com/mail-in-a-box/mailinabox/issues/2120 https://github.com/mail-in-a-box/mailinabox/issues/2004 https://github.com/mail-in-a-box/mailinabox/issues/1885

This is related to a step on nextcloud configuration that should not be touching that directory, yet they attempt to do it anyway. The problem with this comes up because when upgrading versions we need to unlock said directory first (which we don't).
