Polybase with SQL Server 2019 on Linux or Containers I would like to install SQL Server 2019 on Linux either a full Linux server (Ubuntu 18.04) or on a Docker container with Polybase.  Installing MSSQL 2019 on a Linux Server or a container is relatively easy.  It's the Polybase bit that I cannot figure out.
Using the instructions at this Microsoft Docs site:  https://docs.microsoft.com/en-us/sql/relational-databases/polybase/polybase-linux-setup?view=sql-server-ver15
There is a reference to install Polybase on Ubuntu, which should be applicable in both cases (server or container).  When I attempted to install the Polybase packages on an Ubuntu server I got this result:
sudo apt-get install mssql-server-polybase
Installed without any issue
sudo apt-get install mssql-server-polybase-hadoop
The following packages have unmet dependencies: mssql-server-polybase-hadoop : Depends: mssql-zulu-jre-11 but it is not installable E: Unable to correct problems, you have held broken packages.
I could not find a solution to installing the package mssql-zulu-jre-11 on a Linux Server.
In a container, I logged in as a Root user and attempted the commands above:
apt-get install mssql-server-polybase
E: Unable to locate package mssql-server-polybase
I did verify that within the container the Linux instance has the correct sources for apt to find this package.  I am completely confused as to how to get Polybase running with SQL Server 2019 on Linux.  Have any of your had success?  Any help would be greatly appreciated!
After a lot of trial and error and a lot of research, I found a solution.
I tried both Ubuntu 16.04 and Ubuntu 18.04.  This installation approach works for both, but I only was able to get Polybase to work under Ubuntu 18.04.
I performed a fresh install of Ubuntu and SQL Server.  As with every attempt, everything went well except the installation of the mssql-server-polybase-hadoop package. It failed on attempting to find and install the mssql-zulu-jre-11 package.
However, I downloaded the .deb package and manually installed it from these locations:
Ubuntu 16.04:  https://packages.microsoft.com/ubuntu/16.04/prod/pool/main/m/mssql-zulu-jre-11/mssql-zulu-jre-11_11.43.56-1_amd64.deb
Ubuntu 18.04:  https://packages.microsoft.com/ubuntu/18.04/prod/pool/main/m/mssql-zulu-jre-11/mssql-zulu-jre-11_11.43.56-1_amd64.deb
After installing it with dpkg -i, I was able to then install the mssql-server-polybase-hadoop package.
This process allowed me to configure and use Polybase.  (Only with Ubuntu 18.04)
