If you’ve installed Ubuntu from scratch, you may have noticed that the add-apt-repository command is not available by default. This is because the add-apt-repository command is in the python-software-properties package, which is not installed by default. Fortunately, it’s easy to install the python-software-properties package and make the add-apt-repository command available.

How to Fix ‘Add-apt-repository’ Command not Found
What is the ‘add-apt-repository’ command?
The ‘add-apt-repository’ command is used to add new repositories to your Ubuntu system. This is useful if you want to install new software that is not available in the default Ubuntu repositories. For example, if you want to install the latest version of a certain software program, you can use this command to add a repository that contains that program.
To use this command, you will need to specify the repository that you want to add. This can be done by using the ‘-r’ option followed by the repository URL. For example, to add the Ubuntu Extra repository, you would use the following command:
add-apt-repository -r http://archive.ubuntu.com/ubuntu/dists/xenial/main/binary-amd64/
Once you have added the repository, you can then install the software by using the ‘apt’ command. For example, to install the ‘wget’ program, you would use the following command:
apt install wget
If you want to remove a repository that you have added, you can use the ‘remove-apt-repository’ command. For example, to remove the Ubuntu Extra repository, you would use the following command:
remove-apt-repository -r http://archive.ubuntu.com/ubuntu/dists/xenial/main/binary-amd64/
Why is this command not working?
There are a number of reasons why the “add-apt-repository” command might not be working on your system. Here are a few potential causes:
1. You might not have the “software-properties-common” package installed. This package provides the “add-apt-repository” command. Try running “sudo apt-get install software-properties-common” to install it.
2. You might be using an older version of Ubuntu that doesn’t have this command. The “add-apt-repository” command was first introduced in Ubuntu 9.10. If you’re using an older version of Ubuntu, you can either upgrade to a newer version, or use an alternative method for adding repositories.
3. There might be a problem with the repository that you’re trying to add. If you’re encountering an error when running the “add-apt-repository” command, it’s likely that there’s a problem with the repository itself. Try adding the repository using a different method, or contact the repository maintainer for help.
