Mozilla's email client Thunderbird 3 was released just a few days back. In the release page, however only the .tar file was available for Linux. In this post we will show you how to install Thunderbird 3 in Ubuntu 9.10 from the Mozilla PPA.

• Add the Mozilla PPA in your source list using:

sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa

• Update source list using:

sudo apt-get update

• Install Thunderbird 3 using:

sudo apt-get install thunderbird-3.0

It is advised that you remove the repository from the source list after the installation. If you do not know how to do it, here is how:

• In Terminal, execute the command,

sudo rm /etc/apt/sources.d/sourceubuntu-mozilla-daily-ppa-karmic.list

sudo rm /etc/apt/sources.d/ubuntu-mozilla-daily-ppa-karmic.list.save

sudo apt-get update

• Save and close the file. Done.
