RUN apt-get upgrade
RUN apt-get update
RUN apt-get -y install apt-transport-https curl

A note in passing: try to reduce the number of layers in your image by minimizing the number of separate RUN commands in your Dockerfile. − docs.docker.com/develop/dev-best-practices – Spritsail

Answer 1

Seems related to this bug:
https://bugs.launchpad.net/ubuntu/+source/ca-certificates-java/+bug/1998065

Try to install ca-certificates-java before java, e.g.:

apt-get install ca-certificates-java openjdk-11-jre-headless

Rocket

Answer 2

It's some layering issue I read somewhere else online. Don't know much about that. But that pointed me toward a usable fix: remove the folder and recreate it.

rmdir /etc/ssl/certs/java
mkdir /etc/ssl/certs/java

Now the install should work.

Unprofitable

Answer 3

It works for me (important the two separated RUN commands in this order)

RUN apt-get install -y ca-certificates-java
RUN apt-get install -y default-jdk
