This idea that GPG signatures on the index files is enough has been
totally disproven. There was a bug in apt where Debian devices could be
exploited by feeding them crafted InRelease files:
If HTTPS was used, that would mean exploiting that would require
compromising the mirror servers. With HTTP only, anyone that can see
the network traffic can exploit the Debian box. Plus there are other
things that using HTTPS improves:
HTTPS does not entirely solve all these problems, but it does
drastically improve things.
