From "sudo apt-get update" and "sudo apt-get install openssh-server" I cannot install the current openssh version 5.9. I was looking for openssh backporting package however if I am not wrong it does not exist (looking at the wrong place?). I was thinking about importing some repos from ubuntu 11.10, however I am not so confident with this solution. I tried to download a deb package from launchad, however there are obviously missing some dependencies. What I am suppose to do to install a new version? What is the best way to update openssh?

ps: missing library is libssl1.0.0

Thank you
