>             Project: Flink
>          Issue Type: Bug
>          Components: Build System / CI
>    Affects Versions: 1.17.2, 1.19.0, 1.18.1
>            Reporter: Matthias Pohl
>            Assignee: Matthias Pohl
>            Priority: Major

>             Fix For: 1.20.0

> The current CI Docker image is based on Ubuntu 16.04. We already use 20.04 for the e2e tests. We can update the Docker image to a newer version to be on par with what we need in GitHub Actions (FLINK-33923).
> This issue can cover the following topics:
>  * Update to 22.04
>  ** OpenSSL 1.0.0 dependency should be added for netty-tcnative support
>  ** Use Python3 instead of Python 2.7 (python symlink needs to be added due to FLINK-34195) 
>  * Removal of Maven (FLINK-33501 makes us rely on the Maven wrapper)
