add-apt-repository − Adds a repository into the /etc/apt/sources.list or /etc/apt/sources.list.d or removes an existing one
add-apt-repository [OPTIONS] REPOSITORY
add-apt-repository is a script which adds an external APT repository to either /etc/apt/sources.list or a file in /etc/apt/sources.list.d/ or removes an already existing repository.
The options supported by add-apt-repository are:
-h, --help Show help message and exit
-r, --remove Remove the specified repository
-y, --yes Assume yes to all queries
-k, --keyserver Use a custom keyserver URL instead of the default
REPOSITORY can be either a line that can be added directly to sources.list(5), in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.
In the first form, REPOSITORY will just be appended to /etc/apt/sources.list.
In the second form, ppa:<user>/<ppa-name> will be expanded to the full deb line of the PPA and added into a new file in the /etc/apt/sources.list.d/ directory. The GPG public key of the newly added PPA will also be downloaded and added to apt’s keyring.
In the third form, the given distribution component will be enabled for all sources.
