add-apt-repository:tldr:33404

The command "add-apt-repository --enable-source ${repository_spec}" is primarily used in Debian-based operating systems to add a repository and enable the source code repository for the specified repository specification.

Here is a breakdown of the different components of the command:

• "add-apt-repository": This is the actual command to add a new repository.
• "--enable-source": This option is used to enable the source code repository for the repository. Enabling the source code repository allows you to download and explore the source code of the packages from that repository. It is particularly useful if you want to make modifications or understand how the software is built.
• "${repository_spec}": This is a placeholder for the actual repository specification. You should replace it with the specific repository you want to add. The repository specification could be in different formats, such as a URL or a PPA (Personal Package Archive) repository.

By executing this command with the appropriate repository specification, you will add the specified repository to your system's list of available repositories and enable the source code repository associated with it.
