We are now rolling-out Maths Linux Desktop 22.04 jammy ... using the Tuesday night maintenance window.

Our intention is to offer our Maths Desktop users a choice for when they may upgrade and we expect to run the updated desktops alongside the existing option for around a year. For clarity: we are not likely to mandate this update until March 2024.

Each Maths Desktop option follows the release schedule of Ubuntu - which has an expected lifetime of 3-5 years. Some components only receive updates for 3 years so we would generally advise to update sooner (April 2023).

Please send any feedback to help@maths.cam.ac.uk

We intend to keep this page updated with more information and answers to common questions.
You should find a poster next to each of the test machines with a link to this website.

When will the 20.04 focal option disappear?

We expect to continue to offer support for the 20.04 Maths Desktop Linux build until around April 2024

When will the 22.04 jammy option become default?

We expect that all new machines and rebuilds will be deployed with 22.04 starting in April 2023

How long will 22.04 jammy be supported?

Each Maths Desktop Linux option follows the release schedule of Ubuntu - which has an expected lifetime of 3-5 years.

Some components only receive updates for 3 years and we expect to be rolling out a new version every 2 years.

We expect to support 22.04 jammy until April 2026 but advise moving to a putative even newer build from March 2025.

Why are these machines slow?

Please be aware that some of these machines are quite old and are certainly not the fastest in the fleet - please be patient if they seem a tad sluggish.

We believe the experience on most of our desktops should be similar to the 20.04 build.
