I suggest looking here for information on apt:
http://www.debian.org/doc/manuals/apt-howto/index.en.html
Once a Sarge or Sid repository has been added to
/etc/apt/sources.list, the commands needed are:
apt-get update
apt-get install pan
I have no idea of what you are talking about. I went to the link
provided but didn't understand what I read. I see none of the
things people have mentioned on the Xandros desktop.
I've never used Xandros, but because it's Debian-based you should
basically need three steps:
1. Add a line like this to the /etc/apt/sources.list text file:
deb http://http.us.debian.org/debian testing main contrib non-free
2. From the command line execute "apt-get update"
3. From the command line execute "apt-get install pan"
After you've installed the package you might want to comment out
or remove the line from /etc/apt/sources.list.
