I would like to use an ubuntu 20.04 based build agent.
When I pull an image the following way `docker pull jetbrains/teamcity-minimal-agent:EAP` and exec into a container it looks like it is an 18.04 ubuntu.
buildagent@a653ba063f93:/$ cat /etc/lsb-release
DISTRIB_DESCRIPTION="Ubuntu 18.04.5 LTS"
How can I use a 20.04 build agent?
