Enable and Install UEK Release 6 on Oracle Linux 7 or Oracle Linux 8 Update 1

Simon Coter-OracleApr 29 2020 — edited May 1 2020

Following technical article will share all the steps required to enable and install Unbreakable Kernel Release 6 on Oracle Linux 7 as well Oracle Linux 8.

As you can see from the blog article "Oracle Linux and Unbreakable Enterprise Kernel (UEK) Releases", UEK6 is today available for:

Oracle Linux 7 Update 7
Oracle Linux 7 Update 8
Oracle Linux 8 Update 1

while, presumably, the same will be part, by default, of the next Oracle Linux 8 Update 2 release.

Note: the installation of UEK6 on Oracle Linux won't replace and/or upgrade existing UEK releases installed on your system; the same will only add UEK6 to the system, and the the system can still be booted with any installed kernel.

Following steps will leverage RPMs available for free on yum.oracle.com website:

Verify the list of Yum repositories enabled on your Oracle Linux 7 or 8 system; "ol7_latest" or "ol8_latest" Yum channels have to be enabled

# yum repolist

Example:

[root@ovirt: ~]# yum repolist

Loaded plugins: versionlock

repo id repo name status

!ol7_UEKR5/x86_64 Latest Unbreakable Enterprise Kernel Release 5 for Oracle Linux 7Server (x86_64) 153+33

!ol7_gluster6/x86_64 Oracle Linux 7Server Gluster 6 Packages (x86_64) 33+13

!ol7_kvm_utils/x86_64 Oracle Linux 7Server KVM Utilities (x86_64) 410+31

!ol7_latest/x86_64 Oracle Linux 7Server Latest (x86_64) 14,471+4,045

!ol7_optional_latest/x86_64 Oracle Linux 7Server Optional Latest (x86_64) 11,391+2,294

!ovirt-4.2/x86_64 Latest oVirt 4.2 Release (x86_64) 243+83

!ovirt-4.2-extra/x86_64 oVirt 4.2 Extra (x86_64) 171+74

!ovirt-4.3/x86_64 Latest oVirt 4.3 Release (x86_64) 138+56

!ovirt-4.3-extra/x86_64 oVirt 4.3 Extra (x86_64) 116+44

repolist: 27,126

Update your Oracle Linux 7 or Oracle Linux 8 system

# yum update -y

Install "yum-utils" RPM on your system; this RPM will install "yum-config-manager", python script that will be used to enable new Yum channels
- Oracle Linux 7

# yum install yum-utils -y

Oracle Linux 8

# dnf install yum-utils -y

With the system updated, you should have following Yum configuration file containing the details related to UEK6

Note: the file name could be "uek-ol8.repo" if you're running on Oracle Linux 8.

# cat /etc/yum.repos.d/uek-ol7.repo |grep -A4 UEKR6

Example:

[root@ovirt: ~]# cat /etc/yum.repos.d/uek-ol7.repo |grep -A4 UEKR6
[ol7_UEKR6]
name=Latest Unbreakable Enterprise Kernel Release 6 for Oracle Linux $releasever ($basearch)
baseurl=https://yum$ociregion.oracle.com/repo/OracleLinux/OL7/UEKR6/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=0

Enable "ol7_UEKR6" or "ol8_UEKR6" Yum repositories on your Oracle Linux 7 or 8 system
- Oracle Linux 7

# yum-config-manager --enable ol7_UEKR6

Oracle Linux 8

Note: on Oracle Linux 8 the "ol8_UEKR6" Yum repository should be enabled by default; if it's not, you can proceed with the following step

# yum-config-manager --enable ol8_UEKR6

Get "Unbreakable Enterprise Kernel Release 6" installed on your Oracle Linux 7 or Oracle Linux 8 system.
- Oracle Linux 7

# yum update -y

Example:

[root@ovirt: ~]# yum update -y
