Debian package needs java dependency #31845
Description
Elasticsearch version: 6.3.1
Plugins installed: []
JVM version: any
OS version Debian or Ubuntu
Description of the problem including expected versus actual behavior:
elasticsearch debian package must list dependency on java runtime.
Both Debian and Ubuntu have the same names for default java runtimes.
current Depends field looks like this:
Depends: bash, libc6, adduser, coreutils
while it should look like something like this:
Depends: bash, libc6, adduser, coreutils, openjdk-10-jre-headless | openjdk-8-jre-headless | java8-runtime-headless | java8-runtime | java10-runtime-headless | java10-runtime
If people want to use different version of java, they can always use update-alternatives command to update default version.
Steps to reproduce:
let's say you have apt sources configured.
simple install never worked, but now it also fails before it even tries to unpack:
root@69db9738979c:/# apt install elasticsearch

OK, since that never worked, I install desired openjdk version together with elasticsearch, and it used to work before:
root@69db9738979c:/# apt install openjdk-8-jre-headless elasticsearch
<skip long installation log>
dpkg: error processing archive /tmp/apt-dpkg-install-9DAxH4/33-elasticsearch_6.3.1_all.deb (--unpack):
subprocess new pre-installation script returned error exit status 1
Errors were encountered while processing:
/tmp/apt-dpkg-install-9DAxH4/33-elasticsearch_6.3.1_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
so it still ends with error, also leaving all java packages unconfigured.
It works only if I install java runtime separately, before elasticsearch
This happens because elasticsearch package doesn't have direct dependency on jre. If there is one, package manager would configure jre before trying to unpack elasticsearch.
