Cumulative Update 5 for SQL Server 2017

To update Linux to the latest CU, you must first have the Cumulative Update repository configured. Then, update your SQL Server packages by using the appropriate platform-specific update command.

For installation instructions and direct links to the CU package downloads, see the Release notes.

IMPORTANT

If you use the Query Store feature, and you have previously installed Cumulative Update 2 (CU2) (14.0.3008.27), the following requirement applies to you:

After you install Cumulative Update 3 (CU3) (14.0.3015.40) or a later CU, you must immediately run the following script to delete all plans that were collected by Query Store while CU2 was installed:
