Better option looks like to specify the OS distribution and update the Docker install to be the version based on carlossg/docker-maven#221

• https://docs.travis-ci.com/user/reference/focal/
• https://docs.travis-ci.com/user/docker/#installing-a-newer-docker-version

Can we control what docker version is used by travis?

With "csanchez/maven:3-openjdk-8" and "csanchez/maven:3-openjdk-11" the first 2 jobs passed, only the ARM job failed.
