Update Pack 4 is out!

Introduction

Update Pack 4 was released as the “latest” update pack today. If you’re not using Linux Mint Debian, please ignore this post.
In Update Pack 4, the following significant changes occur which might cause regressions on your system:
  1. Gnome 2 gets “upgraded” to Gnome Shell
  2. The Linux kernel is upgraded to version 3.2

Changing your repositories

Please skip this paragraph if you already updated your APT sources for Update Pack 3.
Before you apply the updates for Update Pack 4, make sure you’re pointing to the correct repositories.
Edit your APT sources by running the following command in the terminal:
gksu gedit /etc/apt/sources.list
Within this file, replace the following:
  • Replace security.debian.org with debian.linuxmint.com/latest/security
  • Replace debian-multimedia.org with debian.linuxmint.com/latest/multimedia
Your APT sources, should now look like this:
deb http://packages.linuxmint.com/ debian main upstream import

deb http://debian.linuxmint.com/latest/security testing/updates main contrib non-free
deb http://debian.linuxmint.com/latest/multimedia testing main non-free
Save and close the file.

Using the Update Manager
