I got the same failure message, but in a different context? I'm testing an Edubuntu server (amd64) installation dist-upgrade and got the 'installArchives() failed' during restarting the DHCP server. I will attach the logs (note that I encountered other problems earlier in the upgrade process, so those will show up in the logs too, cf. bug 67133 about nfs-kernel-server).
