I wanted to update my owncloud 8.2.3-2.1 through apt-get to the actual 9.1.4-2.1
apt-get install --only-upgrade owncloud
but missed the very important fact that I must not jump over the 9.0
So I couldn't update the DB via Web or occ and had to go back to 8.2, I thought.
But I didn't find the exact 8.2 repository on the repository site so I added the 8.2 which gave me exactly the 8.2.10-1.1
I downgraded to this and did the occ (on the website I got that Possible CSRF attack. Connection will be closed. Error) and got no error with occ.
But now all my logins dont work anymore.
I guess this is by overwriting the db by the "update" (which was not the right version).
Is there a way to login again?
