How to Install Adobe Flash in Debian

How to Install Adobe Flash in Debian Lenny/Squeeze/Sid

Flash Player is a cross-platform browser plug-in that delivers breakthrough Web experiences to over 98% of Internet users.

Method 1

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
