Fix ‘add-apt-repository command not found’ Error on Ubuntu and Debian

This quick tutorial shows you how to quickly fix the “add-apt-repository command not found” error on Debian, Ubuntu and other Debian-based Linux distributions.

One of the many ways to install software on Ubuntu or Debian is to use a PPA (Personal Package Archive).

If you want to add a new PPA repository, you’ll have to use the add-apt-repository command in the following fashion:

sudo add-apt-repository ppa:some/ppa

In Debian, elementary OS and sometimes on Ubuntu, you’ll see the error that the add-apt-repository command is missing.

sudo: add-apt-repository: command not found

Let’s see how to fix this annoying error.

Fix add-apt-repository: command not found error

The error is simple. The package add-apt-repository is not installed on your system.

But if you try to use sudo apt-get install add-apt-repository, it won’t work.

It’s because the add-apt-repository command is part of package software-properties-common and you need to install this package in order to install add-apt-repository.

So open a terminal and use this command:

sudo apt-get install software-properties-common

The command’s output will be something like this:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following NEW packages will be installed:
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

Once you’ve installed software-properties-common, you should update the system using this command:

sudo apt-get update

You can now comfortably use add-apt-repository or apt-add-repository commands to add PPAs.

Note: If you see an error saying software-properties-common command not found, you should run sudo apt-get update and then try to install it again.

I hope this quick tip helped you fix the “add-apt-repository: command not found” error on Ubuntu and other Debian-based Linux distributions.

If you’re still facing issues with PPAs, let me know in the comments section. Additional suggestions, questions or a quick word of thanks are always welcome.

    Package software-properties-common is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source

    E: Package ‘software-properties-common’ has no installation candidate.
    Idk what to do.

  • So I am using a live Ubuntu USB to do some software recovery. I tried the install software-properties-common option and it says it is already installed but is set to manually installed. Any recommendations for this issue?

    • The message means that the package in question is installed explicitly, not as a dependency on another package. Usually, packages like software-properties-common are installed as a dependency of other package. When you remove the main package, these dependency packages are also removed. Since you chose to manually install it, now it won’t get removed automatically.

  • After I run this script “sudo apt-get install software-properties-common”.

    here is the result:

    software-properties-common is already the newest version (2.0.7).

    Then I am trying to run “sudo add-apt-repository “deb [arch=amd64] $(. /etc/os-release; echo “$UBUNTU_CODENAME”) stable”

    But still I am having this issue:
