After install LAMP via Tasksel I cannot log in anymore via SSH: connection refused. I'm sure that install LAMP this way causes this problem. I had this once before.
I'm still connected via SSH, so I'm able to fix it now. How can I fix SSH?
Sorry, maybe I was a bit to fast with posting a question. But I was in panic ;) Installing openSSH via Tasksel fixed my problem.
Filled in bug report on Launchpad
