Configuring MSSQL Server on ubuntu - Cannot open or read the persistent registry: \SystemRoot\security.hiv

I'm using the following guide to install MSSQL server on my ubuntu 16.04 machine https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-ubuntu?view=sql-server-2017

when I'm running:

sudo /opt/mssql/bin/mssql-conf setup

no matter what kind of SQL Server edition I choose, I'm getting the following error:

    Confirm the SQL Server system administrator password: 
Configuring SQL Server...

This program has encountered a fatal error and cannot continue running at Mon Apr  1 16:06:07 2019
The following diagnostic information is available:

also I found this post, which look like this guy had a similar problem, but sadly no solution

does any one knows how to solve my problem?

Thank you

Edit: after implementing the answer I got another error:

Confirm the SQL Server system administrator password: 
Configuring SQL Server...

Initial setup of Microsoft SQL Server failed. Please consult the ERRORLOG in /var/opt/mssql/log for more information

To make some clean in the mess that I had in the log folder I decided to delete it completely using

sudo rm -rf /var/opt/mssql/log

and re-run the setup, Apparently that solved my last problem and finally: Setup has completed successfully. SQL Server is now starting.

You'll find further information in

/var/opt/mssql/log

So I ran locate to see where "systemroot" is located:

locate security.hiv
/var/opt/mssql/.system/system/security.hiv

I didn't know which permissions should be applied, so I just gave read&write to "others".

then the same with

lsa.hiv
licensing.hiv

re-run

sudo /opt/mssql/bin/mssql-conf setup

and then, sql-server starts, plus the permissions for others are gone again.

By the way, you can run sql-server without service, then it works even if the service fails:

/opt/mssql/bin/sqlservr
