Apparently, there's now a thing called `packagekit` whose daemon seems to like to download updates "in the background" for me.
Thanks, but no, thanks. This tends to occur at inopportune times for me and it's not far enough "in the background", so it gets in the way (furthermore, I like to download my packages with `debdelta` and `packagekitd` doesn't know how to do that, AFAICT). How can I stop those downloads? Currently, I did systemctl mask packagekit which might get the job done, but I don't really know what other impact it might have, and I see that APT complains about it (tho it still works fine, as far as I can tell): # LANG=C apt update Hit:1 http://deb.debian.org/debian stable InRelease Hit:2 http://security.debian.org stable-security InRelease Hit:3 http://security.debian.org testing-security InRelease Hit:4 http://deb.debian.org/debian testing InRelease Hit:5 http://deb.debian.org/debian unstable InRelease Error: GDBus.Error:org.freedesktop.systemd1.UnitMasked: Unit packagekit.service is masked.
