Assuming you meant that you ran the command (you didn't put it in a "Code:" block, like this):
Code:
apt-get install boot-floppies
then you are trying to install the package
boot-floppies.
Unfortunately, I cannot find any evidence that such a pkg. currently exists in Debian:
http://packages.debian.org/search?ke...ll§ion=all
yields "Sorry, your search gave no results", even though it is specifically mentioned in:
http://www.debian.org/releases/slink...chinfo.en.html
Installing Debian GNU/Linux 2.1 For Alpha
version 2.1.11, 28 August, 1999
which is waaay out of date.
Perhaps a little more explanation from you would help.
