I can make a connection to SQL Server at first, using it with DBeaver for 1 week. Today I wanted to change the sa password, so I ran

sudo /opt/mssql/bin/sqlservr-setup


...but it seems to have failed. I removed the SQL Server package and installed it again, but the password for sa always gives me that kind of error. I can't make any connection again because of password failure.

How can I perform a fresh installation? I have deleted all mssql on /opt but no luck. Or how can I change the current sa password?
What OS are you using?

To get a fresh installation you have to remove the data directory, after removing the mssql-server package:


  sudo yum remove mssql-server 
  OR 
  sudo apt-get remove mssql-server 


And then:


  sudo rm -rf /var/opt/mssql


This will delete all your user databases, but will also remove the system databases, which will allow you to reinstall and, hence, re-specify the SA password upon reinstall. 

Let me know if this works.
