PPA for Ubuntu

(source: https://answers.launchpad.net/taskcoach/+faq/1615)

The benefit of installing Task Coach via the PPA is that it will be updated
along with the rest of your system's software whenever you install updates.

There are three basic ways to add the PPA in Ubuntu:

Method #1: Synaptic

1. Launch Synaptic
2. In the "Settings" menu, choose "Repositories"
3. Go to the "Other software" tab and click the "Add" button
4. Enter the source: ppa:taskcoach-developers/ppa
5. Click the "Add source" button
6. Once back in Synaptic click the "Reload" button
7. Search for Task Coach in the package list and select to install

Method #2: Software Center

1. Launch Software Center
2. Choose "Software Sources..." from the "Edit" menu
3. Go to the "Other software" tab and click the "Add" button
4. Enter the source: ppa:taskcoach-developers/ppa
5. Click the "Add source" button
6. Wait for the Software Center to refresh the sources list
7. Search for Task Coach in the package list and select to install

Method #3: Command line

1. Bring up your favorite terminal emulator (NOTE: if you don't have one
   or don't know how, maybe you should try methods #1 or #2!)
2. Enter the following three commands:
   • sudo add-apt-repository ppa:taskcoach-developers/ppa
   • sudo aptitude update
   • sudo aptitude install taskcoach

If you don't have aptitude installed, you can simply replace that
with apt-get in the above commands.
