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. -- Liam
