Strange "app-navigation" page after upgrading to Nextcloud 19

Hi, you could try this:

File is locked - how to unlock

solved the issue for me, thanks. sudo -u www-data php occ maintenance:mode --on (in Nextcloud folder) sudo redis-cli -s /var/run/redis/redis.sock flushall (OK was response) exit sudo -u www-data php occ maintenance:mode --off (in Nextcloud folder) sudo -u www-data php occ files:scan --all (in Nextcloud folder) But there was no password in redis? Is this right?
