Universe – Free and open-source software from the Linux community.Main – Free and open-source software from the Ubuntu developers.By default, each Linux distribution grants access to a set of basic, default repositories. A repository is a database of many different software packages. Additionally, a package manager automatically keeps track of all installed software and updates.Ī package manager works in tandem with a software repository. If there are any dependencies, the package manager installs those as well. In certain cases one package needs other packages (called dependencies) to run.Ī package manager does the work of loading the software package you want. What is a Repository in UbuntuĪ software package is an application. In these cases, the add-apt-repository command is the key to grant access to the software you want to install. Such as in the case of Debian, restrictive licensing may disqualify a package from being included in the default repositories. Other software may be subject to additional licensing. To install the latest version of Wine on Ubuntu, you first need to grant access to the Wine repository: sudo apt-add-repository ‘deb bionic main’ But the latest version isn’t available through the default repositories. This is when the add-apt-repository command is used.įor example, Wine is a popular package for running non-Linux software on a Linux system. To make installing easier, developers created their own software repositories. Sudo apt install python-software-properties How to Add Apt Repository in Ubuntu & DebianĬertain software packages aren’t included in the default repositories. Note: In Ubuntu 13.10 (and older), the add-apt-repository command is part of the Python software package.
