Solution 1: Installing the Required Package

The most common and simple way to resolve the sudo add-apt-repository command not found issue is by installing the software-properties-common package. This package contains the add-apt-repository command. Following are steps on how you can do it:

1. Press Ctrl+Alt+T to open a terminal window in the operating system or connect server via SSH to your Debian instance.

2. First we need to update the package list using the following command:

sudo apt update
apt debian update

This will update your Debian repository, If you want to upgrade the package also use the following:

sudo apt upgrade -y

3. Next, you need to install the software properties common package. Type the following command:

sudo apt install software-properties-common
software properties common

4. After installing the package verify that with the following command:

add-apt-repository --help
apt add repo help

If the command displays help information the installation was successful.

Solution 2: Manual Installation

If for some reason you cannot install the software-properties-common package, you can manually install the add-apt-repository command. However, this method is generally recommended for those users who understand technicalities. Following are the steps for manual installation:

1. You need to install the Python package with the help of the following command:

sudo apt install python3-software-properties
python software properties

2. After that you have to create a symbolic link in Linux system. Type the following command:

sudo ln -s /usr/lib/python3*/dist-packages/softwareproperties/ppa.py /usr/bin/add-apt-repository

Replace /usr/lib/python3*/dist-packages with the actual path to your Python site-packages directory.

sudo add-apt-repository "deb https://dl.winehq.org/wine-builds/debian $(lsb_release -cs) main"

Replace $(lsb_release -cs) with the correct code name for your Debian version.

After adding a new repository it is essential to update the package lists as described update command. If you no longer need a repository you can remove it using the ppa-purge command:

sudo ppa-purge ppa:<ppa_name>
