Make a Debian GNU/Linux seedbox with rtorrent and screen

[Hallvor]

Thank you. I have now updated the howto, though I should have done so before: I noticed the same issue about a week ago, and editing the script made the error disappear. Another minor issue I noticed was that the noip2 package was dropped from main. It can be grabbed from Sid and has no dependencies. It works flawlessly on my box.

Edit: Also fixed some broken screenshots from installation.
