Im running Nextcloud on Nethserver 7.9.2009 and Nextcloud popped a mandatory update to 20.0.2 (cant skip or bypass), I continued with the update by pressing Start Upgrade, now nextcloud is unavailable with the following log:

Nextcloud is stuck in maintenance mode.
This is the second time I tried to update Nextcloud in the last 6 months and each time there is an issue.
