SQL Server team has been working diligently in adding support for current Linux distributions. To this end, the team announced support for SQL Server 2019 on RHEL 8.0, Ubuntu 18.04 and SLES 12 SP5 within last quarter.
The team is glad to announce that the Azure marketplace PAYG (Pay As You Go) images for SQL Server 2019 on RHEL 8.0, Ubuntu 18.04 and SLES 12 SP5 have been made generally available. You can deploy these images to get the latest of both SQL Server 2019 functionality and operating system improvements.
With Ubuntu 20.04 coming out soon, it’ll be interesting to see when that officially becomes supported.
