Here’s stuff that I forget. Like how to install something from Debian backports.
apt-get install debian-backports-keyring
apt-get -t etch-backports install package-name
Don’t forget to add to /etc/apt/sources.list:
deb http://www.backports.org/debian etch-backports main contrib non-free
It’s not a bad idea to make sure that etch-backports then updates that file. So pin it in /etc/apt/preferences (that file might not exist):
Pin: release a=etch-backports
