4 Mate - Add Mint Main Repository

To install Mate, you first need to add the Linux Mint repository to your sources. To do that open your sources.list file by entering following:

sudo gedit /etc/apt/sources.list

At the end of the file, add the following line:

[...]
deb http://packages.linuxmint.com/ lisa main upstream import

Save the file and close it afterwards. Before you import the key, update the package list:

sudo apt-get update

Then import the Mint keyring...

sudo apt-get install linuxmint-keyring

... and update the package list once again:

sudo apt-get update

sudo apt-get install mint-meta-mate

To change the wallpaper back to normal, select the Background tab and choose the one you like most. The default Ubuntu 11.10 wallpaper is also available on the list:
