Here we will tie a different RHEL 8.2 system to stay on RHEL 8.2: ~]# subscription-manager register -release=8.2 There may be situations where you decide to do this, but this is not recommended by Red Hat.įirstly, you will need to tell the system that you are tying it to a minor release as soon as you register it, via the subscription-manager tool. If EUS is not enabled, the system will stop receiving any new updates the moment the next RHEL minor version is released. Sticking with a specific minor releaseĪn important note:A system should only be tied to a specific minor release in conjunction with enabling EUS, which is described in the next section.

Red Hat Enterprise Linux release 8.4 ~]# dnf list kernel The results show the system is updated to RHEL 8.4, with the latest update to the RHEL 8.4 kernel 4.18.0-305 activating on next boot: ~]# cat /etc/redhat-release

Now let’s run a full system update (quietly): ~]# dnf update -y -quiet Red Hat Enterprise Linux 8 for x86_64 - AppStream (RPMs) 18 MB/s | 31 MB 00:01 Red Hat Enterprise Linux 8 for x86_64 - BaseOS (RPMs) 14 MB/s | 33 MB 00:02 You can use subscription-manager to assign subscriptions. This system is registered to Red Hat Subscription Management, but is not receiving updates. Updating Subscription Management repositories. Here you can see the installed RHEL 8.2 kernel, as well as a far newer 8.4 kernel available to be installed.
Let’s check the installed and available kernel updates. Red Hat Enterprise Linux release 8.2 (Ootpa) The initial state shows the RHEL 8.2 system not actually being tied to a specific release: ~]# subscription-manager release If you just want to update to the latest packages for your major RHEL release, then it’s one simple command. This is both the default, and simplest approach. 8.4 is also an eligible Extended Update Support (EUS) release, meaning that in the later part of 2021, when RHEL 8.5 is released, those wishing to remain on RHEL 8.4 can subscribe their systems to an EUS repository using Subscription Manager. The EUS repository will receive updated packages, as mentioned previously, until early 2023. Looking at the line for 8.4, there is a period of time where it is an actively developed Minor Release. In the above graphic, you can see the planned Red Hat Enterprise Linux 8 life cycle. While the general RHEL release repository receives all security, bugfix, and enhancement errata, a system subscribed to an EUS release repository will only receive selected backports as per the Red Hat Enterprise Linux 8 Extended Update Support Maintenance Policy. However, if the system has the Extended Update Support add-on and is running an eligible EUS release, then further select updates to that minor version will be available.
It is also available as a stand-alone add-on.Ī given minor release is fully supported for six months, i.e., until the next minor release comes out. EUS is included with some subscriptions, such as all RHEL premium for x86_64 architectures, RHEL for SAP Solutions. Red Hat’s Extended Update Support (EUS) exists so that you can remain on a specific RHEL minor release for an extended period of time, helping you stay with a supported configuration. Each minor release is ultimately just a label for a specific set of packages, baselined, tested, and released at a certain time. Red Hat announced a six monthly minor release cadence with RHEL 8, and at the time of writing RHEL 8.4 is the most recent release. How do we use Extended Update Support so you can stay on a specific minor release for longer? How do we get updates, yet stay on a specific RHEL minor release? This article explains the mechanisms available in Red Hat Enterprise Linux (RHEL) to help make this possible. It’s also typically true for large, business-critical applications that don’t tolerate frequent downtime for updates. Customers often tell me that they need to stay on a specific RHEL minor release in order to maintain a supported configuration for a third-party application, such as SAP for example.
