Manage APT repository sources
TLDR
Add a new apt repository
SYNOPSIS
add-apt-repository [OPTIONS] [LINE]
DESCRIPTION
add-apt-repository is a Debian/Ubuntu utility that manages third-party APT repository sources. It can add entries to /etc/apt/sources.list or create individual files in /etc/apt/sources.list.d/, and can also remove previously added repositories.
The tool is most commonly used to add PPAs (Personal Package Archives) from Launchpad, handling both the source list entry and the associated GPG key import automatically. It can optionally update the package cache after modifying sources.
