PPA stands for Personal Package Archive. The PPA allows application developers and Linux users to create their own repositories to distribute software. With PPA, you can easily get newer software version or software that are not available via the official Ubuntu repositories.
As with most things, there are different ways to remove a PPA. You can use your mouse (aka the GUI way) or you can use your keyboard (aka the CLI way).
Here at LinuxAPT, we shall look into the methods for removing a package on Ubuntu using both the GUI and command line.
One of the ways to remove the packages in Ubuntu Linux is using the software and updates app available in the GUI of the Linux.
There are different ways to remove packages using commands in the command line via terminal.
1. Via add-apt-repository
Add or remove packages repositories from the /etc/apt/sources.list.d directory with the add-apt-repository command. Simply use the add-apt-repository command in the following syntax to delete a packages repository from your system. The below command will remove the packages using the apt command:
$ sudo apt-repository -r package_name
For example, using the apt command the packaged erlang solution is being removed:
$ sudo add-apt-repository -r erlang-solution
2. Via the path of lists
The /etc/apt/sources.list.d directory contains all the lists of the available repositories in the Linux system. Path to the directory using the cd command and type ls command to list the repository.
To path to the directory cd command is used:
$ cd /etc/apt/sources.list.d
Now, to list all the repositories available in the system type ls command:
Finally, to remove the desired repository use the rm command:
$ sudo rm packages_name
For example, the package erlang solution is removed using the rm command:
$ sudo rm erlang-solutions.list
3. Via purge
The default removal command simply removes software files from the system, but it keeps all configuration files for safety. The configuration and data files are safe if they are accidentally deleted. Use the –purge argument with the below command to entirely erase all data, application, and configuration files:
$ sudo apt remove - -purge [package-name]
For example, the package is removed using the purge command with apt:
$ sudo apt remove - -purge erlang-solutions

How to use PPA ?
Ubuntu provides a platform called Launchpad that enables software developers to create their own repositories. An end user i.e. you can add the PPA repository to your sources.list and when you update your system, your system would know about the availability of this new software and you can install it using the standard sudo apt install command like this.
A repository is a collection of files that has information about various software, their versions and some other details like the checksum.
Each Ubuntu version has its own official set of four repositories:
