So you’ve followed along the docs to install MSSQL server 2019 on ubuntu 18.04 and you’ve encountered the following error:

Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : TCP Provider: Error code 0x2746.
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Client unable to establish connection.

Reason Why it’s Not Working

TL;DR; SQL Server 2017/2019 have a dependency on OpenSSL v1.0, while Ubuntu 18.04 comes with v1.1

Step 1 — Stop SQL Server

sudo systemctl stop mssql-server

Step 2 — Configuration

sudo systemctl edit mssql-server

then add the following line


save and exit

Step 3 — Link OpenSSL

sudo ln -s /usr/lib/x86_64-linux-gnu/ /opt/mssql/lib/libssl.sosudo ln -s /usr/lib/x86_64-linux-gnu/ /opt/mssql/lib/

Step 4-Start SQL Server

sudo systemctl start mssql-server

Now you should be able to login using

sqlcmd -S -U SA
