When I run occ upgrade I get an foreign key error: InvalidArgumentException: Foreign key name “FK…” for table “oc_polls_groups_polls” collides with the constraint on table “oc_polls_groups_polls”.

Disabling the polls app does not help.

I’ve now dropped the FK constraint from the database. Nextcloud is up and running again.

However, it’s unclear whether the polls app will still works. I’m leaving it disabled.
