Sorry to bump my thread but thought this was worth bumping !!

LinuxCoin now has it's own debian repository. Now you can update your system without re downloading your ISO !! For now if you are running prefinal you can do the following.
rm /etc/apt/sources.list
nano /etc/apt/sources.list
and paste the following into that file
deb http://www.mirrorservice.org/sites/ftp.uk.debian.org/debian/ sid main non-free contrib
deb-src http://www.mirrorservice.org/sites/ftp.uk.debian.org/debian/ sid main non-free contrib
deb http://www.linuxcoin.co.uk/apt sensi main
Save that file and continue with the following steps.
apt-get update
apt-get install bitcoin cgminer diablominer guiminer hashkill phoenix poclbm
