[Early Preview] New Ubuntu 20.04 Linux Machine Executor image


We are pleased to share that we will soon launch a new Ubuntu 20.04 machine executor image. This image is already accessible for preview on CircleCI, but is considered unstable for the duration of the early preview which will end on 2nd September 2020 PST. In other words, until the early preview period is over that date, breaking changes may be made to the image to fix issues discovered. After that date, we will officially announce the release of the image.

To try out the new image, specify the image name ubuntu-2004:202008-01 in your .circleci/config.yml configuration:

  image: ubuntu-2004:202008-01

The ubuntu-2004:202008-01 image is similar to the existing ubuntu-1604:202007-01 image but it is based on Ubuntu 20.04 instead of Ubuntu 16.04, and contains updates to software installed on the image. Notably, it has aws-cli v2 installed, rather than aws-cli v1, and OpenJDK 11 is the default instead of OpenJDK 8.

Here is a list of the major software installed on the image:

aws-cli 2.0.52
chrome 85.0.4183
chromedriver 85.0.4183
docker 19.03.13
docker-compose 1.27.4
firefox 81.0.0
go 1.15.2
google cloud sdk 311.0.0
