Upgrade problem from Nextcloud 9 to 10


I’m sorry for my probably very simple to solve upgrade problem here, but I’m stuck and I don’t know what to do anymore :frowning:

It’s not my first owncloud or nextcloud upgrade, so I did what I always do:
mv nextcloud nextcloud.old
tar xf nextcloud10…
cp -r nextcloud.old/data nextcloud/
cp nextcloud.old/config/config.php nextcloud/config/
chown -R www-data:www-data nextcloud
cd nextcloud
sudo -u www-data php occ upgrade

Here I’m getting an error, that Nextcloud can’t connect to the database: http://pastebin.com/udPfSKpQ - but the database is in data/owncloud.db, it has sufficient rights and I can even open it manually by issuing: sudo -u www-data sqlite3 owncloud.db and I can do an .open on it and see all the oc_* tables when running the .tables command.

The most problematic thing is that even a rollback to the old nextcloud by exchanging the directories again does not work anymore. Then I get the same error (even though it’s completely the old state). What did I do wrong to screw things up so badly that I can’t even use the old nextcloud folder anymore? Please help me!

Thanks in advance,

Oh, ok, sorry for the inconvenience, the error was in the configuration of the database path. Just ignore this
