I've seen this happen on VirtualBox Windows VMs, and have read reports
of the same problems on real installations too. When the VirtualBox VMs
are running Windows Update, tcpdump reports that the guests are
connecting to MS IP addresses over HTTPS, and I have no reason to
believe that there is a network fault. The only workaround I know is to
leave the update running overnight. So far I have found that the update
always reaches completion ... eventually.
It's pretty pathetic, when you consider that APT can update an entire OS
in just a couple of hours.
