Hi Didier,

Pls note that I'm using Ubuntu Linux not Amazon Linux2.

Thanks.

One more question. If I want to upgrade kernel to specific version (not latest version) without upgrade other application. How I can do?

For example, I'm using kernel 5.15.0-1023-aws and need upgrade kernel to version 5.15.0-1061-aws.

Thanks.
