Upgrading Kernel to next minor version

Latest response

Hi All,
I am currently running RHEL 7.5 with kernel 3.10.0-862.14.4.el7 and I am looking to upgrade the kernel (not anything else) to 3.10.0-957.10.1.el7. I am aware that RH7.6 runs this kernel, so is there a way to use the 7.6 kernel on a 7.5 system? I am specifically looking for the steps involved. I am aware this is not conventional, but my company is running some tests and this is part of the process. Any assistance anyone could provide would be appreciated.

We don't specifically test kernels across minor versions, but that should work.

You can list all available kernel packages with:

yum list available --showduplicates kernel

and install one with:

yum install kernel-3.10.0-957.27.2.el7

If there are any other dependencies required, they should be pulled in by yum.

Hi Jamie, Thank you for taking the time to respond. I did try this and the kernels listed only go up to 3.10.0-862.

You may have the system tied to a specific minor release?

See: How to tie a system to a specific update of Red Hat Enterprise Linux?

The section down the bottom with --releasever and release --set and release --unset.

I did have it set a specific version. I unset it and was able to download it. Thank you very much for your time and assistance.
