How to Remove Unused PPAs from Ubuntu

Launchpad's PPA system is a neat tool that allows you to install new or upgrade existing packages without having to wait for packages from official distribution repositories.

However, if you use PPAs quite frequently, they can pile up slowly and it can become difficult to keep track of unused PPAs overtime.

Thankfully there is a simple bash script that can do all the work for you.

Download the script from here and mark it executable. Run the command below to list all PPAs added to your system.

./checkPPAs.sh

If you find any PPA with no packages installed, run the command below to remove them.

./checkPPAs.sh --delete
