I have an 18.04 host,A, currently running the 4.15.0-124-generic kernel.

The latest is 4.15.0-126-generic.

host A had holds on linux-generic, linux-headers-generic, linux-image-generic so the kernel wouldn't change and mess up the nvidia drivers manually installed from Nvidia. This was done because researchers needed that stability.

I removed the holds, ran apt update, apt upgrade and it the new kernel isn't "found".

I compared the /etc/apt/sources.list files to host B and they have identical hosts.

They are both calling the same repos for the kernel updates, but A isn't "seeing" them.

Additional things tried:

apt clean

checked apt-cache policy for all linux images there and no luck

Have you installed a recent hardware enablement stack? https://wiki.ubuntu.com/Kernel/LTSEnablementStack – Robert Dec 11 '20 at 22:50
We have not. We are sticking with the 4 kernel for these hosts. – gizmo mathboy Dec 12 '20 at 16:18
I tried to update a host and somehow, somewhere the latest kernel was found and installed. No clue what changed or how. I hate these heisenbugs. – gizmo mathboy Dec 16 '20 at 15:01
