Solution for apt-add-repository: command not found
If you’re receiving this error, it means that your system is missing the package that allows it to add PPA repositories. The package you will need to install is called
software-properties-common. Simply follow along with the steps below to get it installed on your system.
- Open a terminal and type the following command to fetch the latest repository updates.
$ sudo apt update
- Next, install the
$ sudo apt install software-properties-common
- Finally, you can add any PPA repository you like. Just for an example, we’ll add the one for Firefox and then use it to install the program.
$ sudo apt-add-repository "deb http://ppa.launchpad.net/ubuntu-mozilla-security/ppa/ubuntu focal main" $ sudo apt update $ sudo apt install firefox
That’s all there is to it. The PPA repository has been added, which allows us to install the software from it after we perform the
apt update command.
