Nextcloud 15: An unhandled exception has been thrown

Sorry, I wasn’t sure where this should go so it went here since it is a relatively fresh install. I setup nextcloud 15 on Ubuntu 18.04 with Apache2, php7, and mysql. It worked well last night so I have to assume that there is some automated process that brought it down overnight, this is actually the second time I have had this same issue and I started over clearing storage and the database.

First I tried to see if I could get anywhere with occ, there is more but it’s too long.
sudo -u www-data php occ

An unhandled exception has been thrown:

I wasn’t able to find any logs for nextcloud itself. /var/log/nextcloud.log is empty

Try making occ verbose with ... occ -vvv status and post output

Here is what I get from occ -vvv excluding the very long header that is to long to post:

You have new mail in /var/mail/root

As far as I can tell these are identical.

I have to call this topic closed because it is now working. I’m not sure how.

::Edit:: It was a permissions issue.

can you elaborate? which file(s) had wrong permissions set? Having exact same problem. No matter what command I input, it gives me exactly what it gave you…
Im furious, my boss is mad (almost 200TB of data of extremely crucial importance is inaccessible because of what? Because of some bug in updater. Dev team is powerless - they have no clue whatsoever…
