Get LTS updates for Debian 6 Squeeze

Debian LinuxDebian Squeeze (6.0) is a kind of “Old Stable” branch of Debian, the official support for this version ended in April 2014. Squeeze is still used on many servers, so a group of Debian developers decided to provide security patches for a longer timespan for this release.

These so called LTS updates (LTS = Long Term Support) are not available on the normal Debian update repository and not every user might be aware of these updates. We’ll explain how to enable LTS repository in Debian 6 Squeeze and install the updates.

Add the new repository
Open the sources.list file with an editor, and add the following 2 lines at the end of the /etc/apt/sources.list file:

deb http://ftp.de.debian.org/debian squeeze-lts main contrib non-free
deb-src http://http.debian.net/debian/ squeeze-lts main contrib non-free

Please note: The updates are only provided for the i386 and amd64 architectures.

Installation of updates
The updates are then installed as usual with apt-get. Run these commands,

sudo apt-get update
sudo apt-get upgrade

Some Limitations
Not all packages get security updates. To run a check if unsupported packages on your Server, we need to install “debian-security-support”.

sudo apt-get install debian-security-support

To check if unsupprted packages are installed is to run this command every time a package is installed,

sudo check-support-status
