Repair SQL Server on Linux after an Ubuntu distribution upgrade

SQL Server 2017 is supported on Ubuntu 16.04 LTS (Long-Term Support), however that version of Ubuntu Linux is now more than two years old, so you may be tempted to update Ubuntu to a more modern release such as Ubuntu 18.04 LTS (Bionic Beaver).

Should I upgrade SQL Server 2008 / R2, or migrate to Azure?

[Last updated July 13, 2018] Brent Ozar Unlimited runs a website called SQL Server Updates which comes in really handy for keeping your on-premises SQL Server up to date. In October 2016 I noticed something interesting: if you’re running SQL Server 2008 or 2008 R2, Microsoft’s extended support for it ends on 9 July 2019.[…]
