Our quarterly new Linux machine images are available. The updated Ubuntu 21.04 and Ubuntu 16.04 images are now available:
This January refresh updates software included in the image, which can be found below. See the machine executor docs for more information about how to use the machine executor and these images.
This release is fairly boring. One fix and just standard updates to the normal pre-installed software. You can view the table below for installed software versions.
For the fix, there was an issue with Python being unable to detect LZMA. This is no longer an issue.
As a reminder, we have a quarterly release cadence for these images. This is the January update meaning the next two Linux image releases will be in April and July.
Ubuntu 16.04 will soon be EOL
Ubuntu 16.04 reaches the end of its LTS window at the end of April 2021 and will no longer be supported by Canonical. As a result, the final 16.04 CircleCI machine image release by us will take place in April to include the most recent security patches. We suggest upgrading to the Ubuntu 20.04 image for continued releases past April, 2021.
Here’s a quick usage example:
version: 2.1 workflows: main: jobs: - build jobs: build: machine: image: ubuntu-2004:202101-01 steps: - checkout - run: echo "Do some things"
Here is a list of the major software installed on each image. If multiple versions are present, the default is shown here:
|Ubuntu 16.04 (ubuntu-1604:202101-01)||Ubuntu 20.04 (ubuntu-2004:202101-01)|
|Google Cloud SDK||324.0.0||324.0.0|
