Change repositories from the preview repository to the GA repository

When you upgrade SQL Server 2017 from CTP 2.1, RC1, or RC2 to the General Availability (GA) release you have to switch repositories. The following sections explain your choice of repositories and how to make the change before upgrading.

Repository choices

It is important to note that there are two main types of repositories for each distribution:


Any version prior to CTP 2.1 must be upgraded to at least 2.1 before upgrading to GA.

  • Cumulative Updates (CU): The Cumulative Update (CU) repository contains packages for the base SQL Server release and any bug fixes or improvements since that release. Cumulative updates are specific to a release version, such as SQL Server 2017. They are released on a regular cadence.

  • GDR: The GDR repository contains packages for the base SQL Server release and only critical fixes and security updates since that release. These updates are also added to the next CU release.

Each CU and GDR release contains the full SQL Server package and all previous updates for that repository. Updating from a GDR release to a CU release is supported by changing your configured repository for SQL Server. You can also downgrade to any release within your major version (ex: 2017).


You can update from a GDR release to CU release at any time by changing repositories. Updating from a CU release to a GDR release is not supported.

Change to a GA repository

To change from the preview repository to one source repository (CU or GDR), use the following steps:

  1. Remove the previously configured preview repository.

    Platform Repository removal command
    RHEL sudo rm -rf /etc/yum.repos.d/mssql-server.repo
    SLES sudo zypper removerepo 'packages-microsoft-com-mssql-server'
    Ubuntu sudo add-apt-repository -r 'deb [arch=amd64] xenial main'
  2. For Ubuntu only, import the public repository GPG keys.

    sudo curl | sudo apt-key add -
  3. Configure the new repository.

    Platform Repository Command
    RHEL CU sudo curl -o /etc/yum.repos.d/mssql-server.repo
    RHEL GDR sudo curl -o /etc/yum.repos.d/mssql-server.repo
    SLES CU sudo zypper addrepo -fc
    SLES GDR sudo zypper addrepo -fc
    Ubuntu CU sudo add-apt-repository "$(curl" && sudo apt-get update
    Ubuntu GDR sudo add-apt-repository "$(curl" && sudo apt-get update
  4. Install or update SQL Server using the GA repository.


    At this point, if you choose to perform a full installation using the quickstart tutorials, remember that you have just configured the target repository. Do not repeat that step in the tutorials. This is especially true if you configure the GDR repository, because the quickstart tutorials use the CU repository.
