[Merge] ~edubuntu-dev/ubuntu-images:noble into ubuntu-images:noble

[Erich Eickmeyer]

Comments inline. This was tested successfully and admittedly still has some bugs to iron out prior to starting image builds. The testing environment was on a Rapberry Pi with a clean install of Ubuntu Server 23.10. This was done according to instructions used per Lukasz.

Agreed, that can be fixed.

Please understand that this wasn't just "thrown together" but tested on an actual Raspberry Pi running a clean install of Ubuntu Server 23.10, just so you understand the environment.

If core22 in particular isn't explicitly stated, the build will fail and did if it was not explicitly stated. This is why it is explicitly stated here. I don't know why the Ubuntu image doesn't have it, but in my testing it failed without this.

Sadly, it was necessary for some reason. Additionally, without this package explicitly stated, it would fail as a dependency of the build being necessary to exist in the chroot environment. Might be a bug with ubuntu-image but I'm not 100% certain.
