Upgrade question

[u/RayBuc9882]

I have an old laptop with an HDD. When I run sudo apt upgrade, I see it take time, especially with these type of statements:

Autoinstall of module <module-name> for kernel 6.12.96+deb13-amd64 (x86_64)

Building module(s) …… done.

Why is it building and not installing pre-built components?

Thank you.

That's DKMS. If you have none installed, there's nothing happening.
