Solved ? Here is what I just tried and it seems to be working…
=> Turned off maintenance mode.
sudo nextcloud.occ maintenance:mode --off
=> Reloaded Nextcloud Web Interface, recieved the following.
The files of the app (updatenotification) were not replaced correctly. Make sure it is a version compatible with the server.
=> Disabled updatenotification app
sudo nextcloud.occ app:disable updatenotification
=> Reloaded Web page. It reloaded with the following -
Nextcloud will be updated to version 14.0.5
