It's one of those issues, where the fix is simple and dumb, but hard to find. I was struggling to install default-jre package on Debian 10 Docker container (I suspect it's the same on some versions of Ubuntu). I always got the same error at the end:
... Errors were encountered while processing: openjdk-11-jre-headless:amd64 openjdk-11-jre:amd64 default-jre E: Sub-process /usr/bin/dpkg returned an error code (1) ....
I've tried with different packages default-jdk, default-jre, openjdk-11-jre-headless, openjdk-8-jre-headless and the result was the same.
And the solution is.. drum roll:
To fix the issue simply execute this command mkdir -p /usr/share/man/man1. It seems that java packages require that folder to exist. Installing the man package doesn't fix the issue, you need to create the folder manually.
I think this issue mostly affects docker containers, because they are stripped down distributions which in most cases doesn't even have simple binaries like man, vim etc installed.
