Obtaining Packages for Installation

If you have a subscription to Oracle Unbreakable Linux support, you can obtain the packages for UEK 8 by registering the system with the Unbreakable Linux Network (ULN) and then subscribing it to other channels. See Subscribing to ULN Channels.

If the system isn't registered with ULN, you can obtain most of the required packages from the Oracle Linux yum server. See Enabling Access to Oracle Linux Yum Server Repositories.

When you have subscribed the system to the appropriate ULN channels or to the Oracle Linux yum server, you can proceed to upgrade the system to UEK 8. See Upgrading a System to UEK 8.

Enabling Access to Oracle Linux Yum Server Repositories

Packages for UEK 8 and any associated user space applications are available on the Oracle Linux yum server at https://yum.oracle.com/ in yum repositories that are available for each supported Oracle Linux release.

  • Oracle Linux 9: ol9_UEKR8

Oracle Linux 9

To enable access to the UEK 8 repository on the Oracle Linux yum server, use the dnf config-manager command.

  1. Ensure that you have the latest oraclelinux-release-el9 package installed and updated. 

    sudo dnf install -y oraclelinux-release-el9

    The package contains the yum repository definition for the ol9_UEKR8 repository.

  2. Enable the ol9_developer_UEKR8 repository. 

    sudo dnf config-manager --set-enabled ol9_UEKR8

  3. Install the UEK 8 packages, for example: 

    sudo dnf install -y kernel-uek kernel-uek-devel

    Installing the kernel-uek-devel package also installs the gcc-toolset-14 packages.

  4. Verify the UEK 8 kernel packages are installed, for example: 

    dnf list --installed kernel-uek*-6.12.0-*

Subscribing to ULN Channels

UEK 8 kernel image and user space packages are made available for the each supported Oracle Linux release and platform architecture in the following ULN channels:

  • Oracle Linux 9 (x86_64): ol9_x86_64_UEKR8

  • Oracle Linux 9 (aarch64): ol9_aarch64_UEKR8

The following instructions assume that you have already registered the system with ULN.

To subscribe a system to a ULN channel:

  1. Sign in to https://linux.oracle.com with a ULN username and password.

  2. On the Systems tab, in the list of registered machines, select the link that corresponds to the name of the system.

  3. On the System Details page, select Manage Subscriptions.

  4. On the System Summary page, from the list of available channels, select each of the required channels, then select the right arrow to move the selected channel to the list of subscribed channels.

  5. Select Save Subscriptions.
