kernel is pointing to the wrong headers.

I updated... something. There were some modules that required manual fixing because they were not part of dkms, so I did that. It all looked very minor. I installed linux-headers-6.2.0-24-generic over linux-headers-6.2.0-20-generic. While I was at it, I also upgraded the nVidia graphics drivers and lost my graphics. (That's not what I'm writing about here though.)

When I rebooted, I had no network. It turns out that the module for my ethernet device, igc, is in linux-headers-6.2.0-20-generic but not in linux-headers-6.2.0-24-generic. What's up with that? The problem is that I can't figure out how to get Ubuntu to go back to using linux-headers-6.2.0-20-generic. I tried apt install --reinstall linux-headers-6.2.0-20-generic. It did not work. I could put a softlink from linux-headers-6.2.0-24-generic to linux-headers-6.2.0-20-generic but sounds like begging for big trouble.

Is there a clean, official way of doing this? I looked and I couldn't find anything.

For the .deb files, I'm moving them from my laptop to my desktop with a USB stick.

I don't understand what you did that for and why(???) Up until today, the current HWE kernel was 6.2.0-26, which had a few challenges that were fixed in today's kernel update, which is now 6.2.0-31...

What you just posted doesn't match any of those.

To top that off, the installed kernel header file needs to match the version of linux-generic, linux-modules and linux-modules-extra

I figured it out. All I had to do was go to the "advanced" part of the boot menu and select the correct kernel version there.

And which version was that?

What you've said doesn't quite make sense as grub normally chooses the correct most recent kernel, and that version would pull in the correct header packages as dependencies.
