I've got a few hundred ubuntu machines that I need to update, and I'd like to space it over a week and then once they're all updated, space patching over another week.
Is there a way to just download updates so they're ready a week before actually doing the upgrade with apt-get?
According to its man page, apt-get upgrade --download-only will only retrieve packages; it will not unpack them or install them.
Still according to the man page, apt-get upgrade --no-download --ignore-missing will force APT to use only the .debs it has already downloaded.
