I am attempting to debootstrap a Debian 10 onto a disk that will be used with an APU2D4 board.

However, I am getting stuck selecting the proper kernel package.

Assuming the architecture is the same on my host (which runs debootstrap) and on the target host, will apt-get install linux-image-$(dpkg --print-architecture) (assuming Bash semantics) install the correct kernel? ... or is there another virtual package that is even architecture-agnostic and - perhaps - uses $(dpkg --print-architecture) internally to figure out the appropriate specific kernel package?

NB: I am definitely looking for some virtual package so that I will always get the latest kernel updates.

The APU2D4 is an amd64 system, so the appropriate kernel meta-package is linux-image-amd64. In this instance the last part matches the architecture, but that’s not always the case; see the linux-latest package for details of all the available kernel meta-packages.

To ensure you always get the latest kernel, once linux-image-amd64 is installed, you should always upgrade with apt upgrade or apt-get upgrade --with-new-pkgs so that kernel ABI changes are handled correctly.

  • Thanks a bunch. Isn't apt-get upgrade --with-new-pkgs pretty much equivalent to saying apt-get dist-upgrade, though? – 0xC0000022L Jul 30 at 6:19
  • Not quite: dist-upgrade will install new packages and remove packages if necessary to perform the upgrade; upgrade --with-new-pkgs will only install new packages, it won’t remove any. – Stephen Kitt Jul 30 at 7:48

In this case, yes. apt-get install linux-image-$(dpkg --print-architecture) will install a metapackage that has a dependency on the latest kernel for the given architecture. The .deb package format has no way to specify architecture specific dependencies.
