I was upgrading the openssh-server package using apt-get upgrade on my Ubuntu 7.04 server, in order to fix the debian PRNG security bug. I was doing so over an SSH connection (putty on windows) which I thought was ok but...

The upgrade seems to have hung at the following, it's like it wants me to click "Ok" in the "window" but of course I can't because I'm just in a shell.

Setting up openssh-server (4.3p2-8ubuntu1.5) ... Package configuration

â                                  <Ok>
â                                                                           â

I notice that I can't connect any new ssh sessions to the server anymore, but an existing one I have open still works.

Any ideas how I can proceed?

Ensure the Putty window has focus, then try hitting "Enter". If that doesn't work, hit "Tab" until the "< Ok >" is highlighted and then try "Enter" again.

Sweet, thanks! I had tried hitting "Enter" many times, and practically every other key, but never considered "Tab". Tab to select, then Enter, worked like a charm!! – M. Lucas Jul 7 '09 at 16:07
