Install of apt package is failing

Elastic Stack Elasticsearch

Hi. I'm just getting started with elastic and am having an issue installing the package from the apt repo. Here's the output:

sudo apt-get update && sudo apt-get install elasticsearch

This is a dedicated ubuntu 18.04.1 KVM VM that I just spun up and has plenty of space storage so that's not the issue:

df -h /var

Any suggestions would be greatly appreciated!

OK, I found what the problem is. I extracted the .deb and in DEBIAN/preinst, if it doesn't find java, it just exits with an error code of 1 (the 'echo' statements are never displayed, the install just fails).

I added 'default-jre' to the Depends line of DEBIAN/control:

Depends: bash, libc6, adduser, coreutils, default-jre

Then rebuilt the .deb. It installs successfully if the default-jre package is already installed and installs it as a dependency if it's not:

apt-get install ./elasticsearch-6.4.1-mine.deb

I know you probably don't want to necessarily lock users into using the default-jre package but if they're going through the trouble of installing the elasticsearch package from the repo, that's probably what they'll want to install anyway.
