How to Install Adobe Flash in Debian Etch/Lenny/Sid
If you run Etch you will want to use backport.org
First you need to edit the /etc/apt/sources.list file using the following command
#nano /etc/apt/sources.list
add the following line
deb http://www.backports.org/debian etch-backports main contrib non-free
save and exit the file.
Update the source list using the following command
#apt-get update
All backports are deactivated by default. If you want to install something from backports run:
#apt-get -t etch-backports install “packagename”
If you are using etch and you want apt to verify the downloaded backports you can import backports.org archive’s key into apt:
#apt-get install debian-backports-keyring
If you want to get your packages from backports upgraded automatically the following entry in /etc/apt/preferences should be sufficient:
Package: *
Pin: release a=etch-backports
Pin-Priority: 200
Once you have backports all set up do one of the following commands
#apt-get update
#apt-get install flashplugin-nonfree
