This knowledge base is your go-to resource for configuring repository sources.list file, ensuring you have access to the right packages for your Ubuntu system. Perfect for administrators, developers, and Ubuntu enthusiasts, it ensures easy access to software repositories for updates, security patches, and installations.
How to edit ‘sources.list’ file and add Repo URLs?
Before modifying the sources.list, create a backup using: sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup to ensure safe repository changes.
To change repository sources, open the sources.list file located /etc/apt/ using a command-line editor, such as vi editor or nano editor according to your choice, and copy the code from this knowledge base to the file according to your Ubuntu OS version. For example:
sudo vi /etc/apt/sources.listStarting with Ubuntu 24.04, a new configuration file, /etc/apt/sources.list.d/ubuntu.sources, is used for managing repository configurations. To edit this file, open it with a text editor and configure the repositories as suggested in this article.
sudo vi /etc/apt/sources.list.d/ubuntu.sourcesLong-Term Support (LTS) Versions Repo URLs

deb-src http://old-releases.ubuntu.com/ubuntu/ hirsute-backports main restricted universe multiverseWhen setting up sources.list file, using the correct repository URLs that match the Ubuntu version installed on your system is crucial. Older versions are archived as new Ubuntu versions are released, and their repositories are moved to a URL dedicated to old releases. Starting with Ubuntu 24.04, the system no longer uses the /etc/apt/sources.list for repository configuration. Instead, the new configuration file is located at /etc/apt/sources.list.d/ubuntu.sources. If a version of Ubuntu is no longer supported, upgrading to a newer, supported release is recommended.
This list includes official RockyLinux repositories and some useful third-party repositories for added functionality. Similarly, you can also easily configure the Repo URL list for AlmaLinux, CentOS, CentOS Stream, and RockyLinux. To find the working URLs, visit this link:
