first of all: I am not into programming at all. I just use ubuntu, but have no idea how to fix the most simple problem…

I updated to 16.04. While updating the screen freezed and I had to shut down the computer. After restarting it shows a black screen:

Ubuntu 16.04.1 LTS [laptop-name] tty1 [laptop-name] login:

After typing my login with password it alway gives: login incorrect.

What can I do now?

    Please try and get going on what I posted. Edit your question and I will remove my answer (or edit as we go along). Advice: if you do no want this investigated go for a re-install. Otherwise maybe it is best to get 20 rep and join us in chat here chat.stackexchange.com/rooms/201/ask-ubuntu-general-room – Rinzwind Aug 2 '16 at 17:16

That means you ended in a "server" version (so with no working desktop).

The login in the normal login you see on a server. But it should let you log in with any of your accounts. If it does not more is wrong.

Boot into a live dvd and mount the disk that has your /home/ on it. Go to /home/$USER/ and do a tail -n 100 .xsession-errors and see if it holds errors.

Next check with ls -la in /home/$USER/ that the properties are ...

-rw-------  1 rinzwind rinzwind      57 aug  2 09:03 .Xauthority
-rw-------  1 rinzwind rinzwind     153 aug  2 09:03 .xsession-errors

(the name rinzwind should be your user name) for these 2 files.

Edit your question with the result. If you want we can see if we can get it back up by fixing any errors you found. I assume your password will be correct and it kicks you back to login due to problems with the login part.

If you need it start making a backup of your files now.

You could then forget about it all and re-install. That would get you back and restoring your backup will get you your files back too. All you will be missing is software you installed and settings you changed.

  • I now have a USB with the latest version of ubuntu on it. Could I simply reinstall the system without losing my data? At the moment I am unable to backup anything as I have no access to my data. I don't really get what you described above "Boot into a live dvd and mount the disk…" Passwort and Username are correct but the "non-server" version doesn't accept it. BTW: now it says "tty2" instead of "tty1"... – Till Aug 2 '16 at 20:37
  • Yes but BEST is to make a backup. If you do not format your /home/ it will keep all your files and settings but a backup is a lot more safe. – Rinzwind Aug 2 '16 at 20:41
