As I was explaining, when I tried to add ppa:unit193/encryption repository using sudo add-apt-repository ppa:unit193/encryption -y command on my Ubuntu 22.04 LTS system then I noticed sudo: add-apt-repository: command not found error on the output as shown below. For you, it may be different repo on some other Ubuntu/Debian system.

cyberithub@ubuntu:~$ sudo add-apt-repository ppa:unit193/encryption -y

While the above error could occur due to several reasons but most of the time it occurs due to unavailability of add-apt-repository utility on your system. So to fix the above error, you have to install software-properties-common package on your system by using sudo apt install software-properties-common command as shown below. This will download and install the package from default Ubuntu repo along with all its dependencies.

You may be wondering why we are installing software-properties-common package instead of add-apt-repository utility. It is simply because add-apt-repository comes in packaged with software-properties-common so we have to install this package to get add-apt-repository utility.

After successful installation, if you now try to add PPA repo again then this time you will notice that you are able to add it successfully as shown below. This confirms that add-apt-repository is working as expected and hence the error is successfully resolved.

Sometimes it is also possible that even though you have installed add-apt-repository utility on your system, still you are getting the same error. This can usually happen when you installed the utility in some customized location instead of in system defined binary location such as /usr/bin. To solve this problem, you can add the customized location to PATH environment variable.

export PATH=$PATH:/path/to/add-apt-repository

It is however important to keep in mind that above changes are temporary and is local to current session only. To make the changes permanent, you have to add an entry in either ~/.profile or ~/.bashrc file. Then logout and login to the system to update the changes. This should solve your problem.
