I can't remember how I figured this out but it works for me after doing the following:

In the Dockerfile replace this line: openjdk-14-jre-headless \

with this line: default-jre \

Then I have in my shell history to do the following: sudo add-apt-repository ppa:openjdk-r/ppa sudo docker-compose build --no-cache sudo docker-compose up

Good luck. Let me know how it goes and maybe I have some links stored or notes and I can dig a little more.

sudo add-apt-repository ppa:openjdk-r/ppa

This step is not necessary, but thank you for details.

I've updated the Dockerfile to use the default JRE as you suggested. So now docker should work again.
