Nextcloud upgrade 20.0.6 to 20.0.7 fail

Before the upgrade I disabled the two factor app.(the only blocking one)
The update seems to be gone right, everything looks oke, but NC keeps in maintenance mode for a long time. After a while only calendar is working, eg my files or settings are not reachable anymore. generating a 502 Bad Gateway error. In the logging there’s nothing with failures. So I had to do a rollback to 20.0.06.

What can be wrong?

sudo -u nginx php occ maintenance:mode --off

I’m having the same issue. Any idea on the resolution?

Fixed it here. I went to the apps folder and moved my problem app out of it.

root@cloud:/usr/local/www/nextcloud/apps # mv accessibility/ …
root@cloud:/usr/local/www/nextcloud/apps # ls

Solved with the update to 20.0.8, this update doesn’t complain about the Two-Factor TOTP Provider.
