Focal package doesn't work

[Sam Morrison]

I installed a new focal host with following

apt-cache policy zookeeper
zookeeper:
  Installed: 3.4.13-5build1
  Candidate: 3.4.13-5build1

apt-cache policy openjdk-8-jre-headless
openjdk-8-jre-headless:
  Installed: 8u265-b01-0ubuntu2~20.04
  Candidate: 8u265-b01-0ubuntu2~20.04

Zookeper process starts but you can't connect to it. I get the following error in zookeeper logs

2020-09-30 13:51:35,284 - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@215] - Accepted socket connection from /127.0.0.1:42324
