How can I install a "-generic" Linux kernel version on my EC2 Ubuntu instance rather than the "-aws" version?

Hi,

This documentation will show you how to install user-provided kernels on EC2 instance: https://docs.aws.amazon.com/linux/al2/ug/UserProvidedKernels.html

This way you can use exactly the kernel version you want.

Best,

Didier

Hello!

You can try installing a different kernel(-generic) that you have. Change the kernel using the rescue instance method. Before doing this, take a snapshot or create an AMI, and try it on an instance launched from the AMI or snapshot. Although not confirmed, you can also try it in a test environment where you have the "-aws" kernel.
