Updating Thunderbird on an older Ubuntu installation

I’m running Ubuntu 10.04LTS on my desktop at home and while there’s a year left on updates, my Thunderbird was telling me that it’s about to stop receiving security updates. While I typically don’t care about installing all the latest and greatest (as is obvious by my 10.04!), I don’t want to be using ‘old’ software either. I thought I’d investigate what’s required to update to the latest Thunderbird mail client.
As it turns out, it’s pretty easy.

We simply have to add the Mozilla repositories and re-install it. Below are the commands required to update your Thunderbird. It took only a couple minutes!

sudo add-apt-repository ppa:mozillateam/thunderbird-stable
sudo apt-get update
sudo apt-get install thunderbird
