There are two issues here, I think.
one: can you use apt-cacher to serve up debian packages to the very same
host as it is itself running on? Answer: Yes.
two: can you use apt-cacher to serve up a newer version of apt-cacher on
the machine that is running apt-cacher. Answer: never done it. apt-cacher
is pretty small and pretty stable, but it should work because during the
actual install of a package nothing is being downloaded. The sequence is
download and check package validity first, and then unpack the pachage
and do the actual install. There is no possibility of attempting to run
a program while it is being changed on hard disk.
