Why is libssl1.1 Package Not Available for Installation on Ubuntu 22.04?

Upgrading to a new version of your operating system often brings along exciting improvements and new features, but it can also come with certain challenges. For those upgrading to Ubuntu 22.04, an important change to be aware of is the unavailability of the libssl1.1 package. This package, previously essential for many applications, is absent from the repositories of Ubuntu 22.04. Understanding why this happens and what alternatives are available can help you smoothly transition to the latest Ubuntu version.

The Absence of libssl1.1

The main reason libssl1.1 is not available on Ubuntu 22.04 is due to the lifecycle of software packages. The libssl1.1 package is derived from OpenSSL 1.1, which has been deprecated. Ubuntu 22.04, being a more recent release, aims to provide the latest and most secure software versions to its users. Consequently, it includes OpenSSL 3.0.2 instead. Removing older versions like libssl1.1 is part of maintaining a secure and up-to-date environment.

Impact on Applications

This change primarily affects applications that specifically depend on libssl1.1. When attempting to install such applications, you may encounter errors, such as:

This means that the Ubuntu package manager does not recognize libssl1.1 as a valid package for installation because it has been removed from the default repositories.

Solutions and Alternatives

If you find yourself in need of libssl1.1 for a specific application, here are a few steps you can take to resolve the issue:

Update Application Dependencies: Check if there's an updated version of the application that supports OpenSSL 3.0. Developers often update their software to be compatible with the latest libraries.

Manual Installation: As a temporary measure, you might consider manually downloading and installing libssl1.1. However, this approach is not recommended due to potential security risks and future compatibility issues.

Using Containers: Use Docker or other containerization tools to run your application within an environment that includes libssl1.1. This method can isolate the dependency and prevent conflicts with the host system.

Check Alternative Libraries: Some applications might have alternative libraries or forks that support newer versions of OpenSSL. Investigate whether you can replace the dependency on libssl1.1.

Conclusion

The removal of libssl1.1 from Ubuntu 22.04 repositories underscores the importance of keeping software ecosystems secure and up-to-date. While it might introduce temporary inconveniences, solutions like updating application dependencies or using containers can mitigate these issues. Staying informed about such changes helps ensure a smoother transition when upgrading to newer operating system versions.
