After update (Ubuntu/apt), no login possible anymore! :-(

Steps to reproduce

Just update the owncloud server via apt on Ubuntu 16.04 (from https://download.owncloud.org/download/repositories/stable/Ubuntu_16.04)

Expected behaviour

Users should be able to login

Actual behaviour

If they try to login with the correct password, the login screen is shown again with no message whatsoever.

If they try to login with the correct passwort, the message "Wrong Password. Reset password?" appears.

If they try to reset the password via the e-mail link, they can enter a new password, after which the message: "Private Key missing for user: please try to log-out and log-in again" appears.

The installation is and has always been running without encryption, so the never were any private keys to begin with.

This happens on every account configured for the system. Even when new accounts are created via occ, the same thing happens.

I've also tried uninstalling the installation and reinstalling into an empty directory with a new database. After creating the database and admin user, the same thing happens with the newly created admin.

Server configuration

Ubuntu server 16.04 (64 bit)

ownCloud version: (see ownCloud admin page)
- installed: true

Updated from an older ownCloud or fresh install:
Regularly updated for the last 10 months

Where did you install ownCloud from:
see above

Signing status (ownCloud 9.0 and above):
?

Login as admin user into your ownCloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results into https://gist.github.com/ and puth the link here.

As I said, I cannot login, not even with the admin account.

We're using the OC only for shared calendar and contacts, but cannot access the cloud anymore. Even though we have a database backup (and a running, live database for that matter) , it's no use for us, as we cannot get any calendar or contact access to work. We can't even login anymore. :frowning:

So you have the encryption app activated but are not using it?

It looks that way, yes. It might be that there was a plan to eventually use encryption for private file storage, but so far, the OC installation is not being used to store/share files at all.

In any case, here's what the ownCloud reports:

# sudo -u www-data ./occ encryption:status
  - enabled: false
  - defaultModule: OC_DEFAULT_MODULE

Cheers, Michael.

I had the same problem and it drove me crazy until I tried in incognito and it worked.
So I cleaned my cookies, restarted the browser and I managed to log in normally.
