Adding PPA via terminal
To add a PPA from the terminal, we use the syntax as shown below:
sudo add-apt-repository ppa:shutter/ppa
Here we are adding the PPA of a screenshot tool named Shutter. The command above will create a file under /etc/apt/sources.list.d.
Using PPA in Linux
Personal Package Archives (PPA) is a unique software repository intended for non-standard software/updates. The PPA allows application developers and Linux users to create their own repositories to distribute software. It allows us to upload Ubuntu source packages to be built and published as an apt repository by Launchpad. With PPA, we can easily get newer software versions or software that are not available via the official Ubuntu repositories.
