April 26th, 2018 Ubuntu 18.04 released. A 7th long-term support release of the world’s most popular OSOS available in Desktop, Server, Cloud, and Core versions. Tried quite a bit to install SQL Server 2017 on 18.04, but couldn’t get luck. Investigated quite a bit and came across few reasons. Lot of workaround are mentioned across web, however wondering easiest and simplest way, always.
Potential reason till SQL Server for Linux 2017 CU9 package had dependencies on OPENSSL version(1.0.0) but Ubuntu 18.04 LTS comes with OpenSSL 1.1. Microsoft has update the SQL Server 2017 installation package so it can use libssl1.0.0 pkg. However still found issue while installing today (08-Sep-2018). Realised Microsoft SQL Server on Linux 2017 CU10 was updated but still few changes are required at OS level i.e. Ubuntu 18.04.
Read on for screen shots showing how to fix the problem.
