Code review comment for ~andersson123/autopkgtest-cloud:update-deps-mojo-run-move-pkgs-to-basic

I like this, but I'm puzzled by the move of packages from "apt" to "basic". Do we actually need that? Looks like apt.needs_update and apt.queued_installs (which you leverage to trigger an upgrade) are part of the apt layer:

so AIUI it's the apt layer performing the update/upgrade operation.

Does this work if we keep packages under apt?
