To update SQL Server 2019 on 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 SQL Server 2019 Release Notes.

To upgrade Microsoft SQL Server 2019 Big Data Clusters (BDC) on Linux to the latest CU, see the Big Data Clusters Deployment Guidance.

Starting in SQL Server 2019 CU1, you can perform in-place upgrades for Big Data Clusters from the production supported releases (SQL Server 2019 GDR1). For more information, see How to upgrade SQL Server Big Data Clusters.

For more information, see the Big Data Clusters release notes.

You can verify the download by computing the hash of the SQLServer2019-KB4517790-x64.exe file by using the following command:

certutil -hashfile SQLServer2019-KB4517790-x64.exe SHA256

To apply this servicing update package, you must be running SQL Server 2019.

You might have to restart the computer after you apply this servicing update package.

To use one of the hotfixes in this package, you don't have to make any changes to the registry.

The Servicing Update payload mainly contains other fixes required for the new SQL Server 2019 Big Data Clusters feature and there's a critical fix for SQL Server Failover Cluster named instance.

When you deploy an update to a hybrid environment (such as Always On, replication, cluster, and mirroring), we recommend that you refer to the following articles before you deploy the update:

• Upgrade a failover cluster instance

  Note

  If you don't want to use the rolling update process, follow these steps to apply an update:

  • Install the update on the passive node.
  • Install the update on the active node (requires a service restart).

• Upgrade and update of availability group servers that use minimal downtime and data loss

  Note

  If you enabled Always On together with the SSISDB catalog, see the information about SSIS with Always On about how to apply an update in these environments.

SQL Server CUs are currently multilingual. Therefore, this CU package isn't specific to one language. It applies to all supported languages.

One CU package includes all available updates for all SQL Server 2019 components (features). However, the cumulative update package updates only those components that are currently installed on the SQL Server instance that you select to be serviced. If a SQL Server feature (for example, Analysis Services) is added to the instance after this CU is applied, you must reapply this CU to update the new feature to this CU.

If other issues occur, or if any troubleshooting is required, you might have to create a service request. The usual support costs will apply to additional support questions and to issues that don't qualify for this specific cumulative update package. For a complete list of Microsoft Customer Service and Support telephone numbers, or to create a separate service request, go to the Microsoft support website.

1. In Control Panel, open the Programs and Features item, and then select View installed updates.
2. Locate the entry that corresponds to this cumulative update package under SQL Server 2019.
3. Press and hold (or right-click) the entry, and then select Uninstall.

To uninstall this CU on Linux, you must roll back the package to the previous version. For more information about how to roll back the installation, see Rollback SQL Server.
