Nextcloudpi: update to 15.0.8 fails

When trying to update nextcloud via the ncp web interface I get the following errors:

"* twofactor_totp
Fix permissionsā€¦
Upgradeā€¦
Nextcloud is not installed - only a limited number of commands are available

Command ā€œupgradeā€ is not defined.

Abort
Clean upā€¦
Rolling back to backup /var/www/ā€¦"

Did anyone succeed in updating already?

I upgraded fine. Anybody else seeing this?

Tried again today with 1.13.1 and it worked.
