These changes are planned in the weekend of 17 and 18 September.

What will change?

We will upgrade the Ubuntu release on our servers from 20.04 LTS to 22.04 LTS. This will include newer version of many services. An overview of the most important version changes can be found below. For other services/packages, you can always use the Ubuntu Package Search. The distribution name for Ubuntu 22.04 LTS is "jammy".

Note that any existing Python virtual environments in use will need to be recreated in order to function properly.
