[SOLVED] Error installing apps

I can’t log in to make the needed update.
On a perfectly fine password I get:

Permission denied, please try again.

I tried adding my public ssh key and get:

Unable to set SSH keys.

I enabled/disabled the SSH module and rebooted FreedomBox.

I can not log in with the password on the local machine that is connected to a TV set and a keyboard:

Login incorrect.

I can login to the webinterface with my password. I can even create new admin user and login to their webinterface, but not SSH and not locally.
