Repositories are collections of software packages that can be easily installed, updated, and managed by package management tools like APT (Advanced Package Tool). Ubuntu, a popular Linux distribution, has many repositories available for users to access and install software packages. From this writing, I will make sure you get to learn about some of the best Ubuntu repositories available.
Factors to Choose the Best Ubuntu Repository
When choosing a repository, there are a number of factors to consider, some of these factors are:
- Distribution → Check the repository’s compatibility with your specific Linux distribution.
- Official vs. Third-Party → Official repositories are generally more reliable & secure, while third-party repositories may have a wider range of software but require caution.
- Trustworthiness → Ensure that the repository is maintained by reputable sources to minimize security risks.
- Compatibility → Ensure that the available software in the repository doesn’t introduce conflicts or dependencies & is compatible with your system.
- Community Support → Some repository hosting services have a larger and more active community than others. This can be helpful for finding support and troubleshooting problems.
Types of Ubuntu Repositories
Four official repositories of Ubuntu are Main, Restricted, Universe & Multiverse, which contain different types of software packages. Besides these, some Partner repositories are provided by Ubuntu’s partners but are not free or open source. And there are these Third-party repos, which provide additional software not found within the official repos.
Official Ubuntu Repository List
Check out the following detailed explanation of the four official Ubuntu Repositories along with the Ubuntu Partner repository:
A. Main
The term “Main” refers to the primary repository in Ubuntu, containing exclusively Free and Open-Source Software (FOSS). This repository is enabled by default and ensures that all software offered within it can be freely distributed without any restrictions.
Additionally, all the software in this repository is fully supported by Ubuntu developers & provides security updates whenever they need. An example of this repository is the multimedia player, Rhythmbox, which comes pre-installed in Ubuntu.
B. Universe
Similar to the ‘Main’ repository, the ‘Universe’ repository also offers free and open-source software (FOSS). However, there is a distinction in terms of support. While ‘Main’ is officially supported by Ubuntu developers, the ‘Universe’ repository relies on community support for regular updates. Some software it contains are VLC media player, OpenShot video editor, etc.
C. Multiverse
The Multiverse repository contains non-free, closed-source software, and other software with legal or copyright restrictions. Due to licensing and legal issues, Ubuntu cannot activate this repository by default, and it is also unable to provide patches and update software within it. As it does not contain software that is free & open-source.
D. Restricted
The Restricted repositories are dedicated to hardware-related software, often involving proprietary components. These include drivers for graphic cards, touch panels, network cards, and similar items.
E. Partner
The ‘Partner’ repository, on the other hand, consists of proprietary software that Ubuntu has compiled from its partners.
Third-party Ubuntu Repositories
Third-party repositories are external software repositories that may not be included in the official Ubuntu repositories. They are created and maintained by independent software developers, organizations, or communities.
Top 5 Third-party Ubuntu Repositories
While it’s essential to be extra careful when adding a third-party repository to your Ubuntu system, some reputable and third-party repositories can provide valuable software not found in the official Ubuntu repositories. Some of them are:
1. SNAP
Snap is a software packaging and distribution system developed by Canonical, the company behind Ubuntu. It allows developers to package their applications as Snaps, which are self-contained bundles that include all of the dependencies that the application needs to run. To run any application from snap, just type the following command:
snap install <application-name>2. GIMP
It is a popular open-source image editing software. It provides various tools and features for graphic design and image manipulation. GIMP supports various file formats such as JPEG, PNG, GIF, and PSD. It is highly customizable through plugins and allows users to extend its functionality. Add GIMP to your system through the following command:
sudo add-apt-repository ppa:otto-kesselgulasch/gimp3. WINE
Stands for “WINE Is Not an Emulator”, it is a compatibility layer that allows you to run Windows applications on Linux and other Unix-like operating systems. Instead of emulating a complete Windows environment, WINE provides a translation layer for Windows API calls, allowing Windows software on Linux without needing a virtual machine or dual-boot setup. Add WINE by using the following command:
wget https://dl.winehq.org/wine-builds/Release.keysudo apt-key add Release.keysudo add-apt-repository ‘https://dl.winehq.org/wine-builds/ubuntu/’URL: https://wiki.winehq.org/Ubuntu
4. FLATPAK
Flatpaks are a universal package format. They offer sandboxed applications with their dependencies bundled, making them independent of system libraries. Use the following command to add a flatpak repository to your Ubuntu system:
sudo add-apt-repository ppa:alexlarsson/flatpakURL: https://docs.flatpak.org/en/latest/repositories.html
5. LibreOffice
Provides the latest version of free and open-source LibreOffice office suites. It is a popular office suite that includes applications for word processing (Writer), presentations (Impress), databases (Base), spreadsheets (Calc), graphics editor (Draw) & more. It supports a wide range of file formats and is also compatible with documents created in Microsoft Office. Use the following command to add LibreOffice to your Ubuntu system:
sudo add-apt-repository ppa:libreoffice/ppaURL: https://www.libreoffice.org/
Why NOT Use Third-Party APT Repositories?
Using third-party APT repositories in Ubuntu can bring risks and challenges that users should be aware of. Here are some reasons why one might choose not to use third-party APT repositories:
- Security Risk: Using software without personal auditing requires implicit trust in the software publisher. Third-party APT repositories pose less obvious security implications. Unlike modern packaging systems with sandboxing, APT repositories lack this security feature. There’s no clear security boundary between software from different publishers, including the distribution and third parties.
- Lack of Official Ubuntu Support: When you install a third-party package on Ubuntu, community support for related issues becomes challenging. Even if you experience a bug in an official Ubuntu package caused by a third-party package, the Ubuntu community may not be able to help you. In such cases, you’ll need to reach out to third-party package maintainers for support.
- System Integrity: Some third-party packagers attempt to integrate their packages with Ubuntu to avoid conflicts with official distribution packages. However, predicting future changes in Ubuntu releases is challenging, and conflicts can arise. System upgrade failures often result from third-party repositories that initially worked but later conflicted with updates.
Few Tips to Use Third-Party Repositories Safely
Just because users need to be extra careful while choosing a third-party repository doesn’t mean they don’t use them. Below are some tips you can use while choosing one:
- Only add repositories from trusted sources.
- Check the repository’s website or documentation to ensure it is maintained or regularly updated.
- Keep your software up-to-date.
- Read reviews of the repository before adding it.
- Be careful about installing software from unknown repositories.
Conclusion
To sum up, Ubuntu repositories play a vital role in extending the functionality of your Ubuntu system. Understanding and using them wisely after choosing the best ones that fit your system perfectly can greatly enhance your Linux experience. Always prioritize security and reliability when choosing repositories from third-party PPAs, and keep your system up to date to enjoy a stable & secure computing environment.
