Ok, first of all, I've added ubuntu-devel-discuss@lists.ubuntu.com to my CC list as I thought how I responded to the email would have worked (I don't see it in my local mailing list copy, I tried Ctrl+Shift+L to 'reply to list' in thunderbird, now I am 'replying to all')
It looks like you got the phantom bug I got, so this is my best guess is to resolve archive.ubuntu.com and temporarily add it to the chroot environments "etc/hosts" file... This is because the Ubuntu Core doesn't have nslookup and cannot resolve the IP address. (I guess if you have already resolved it, it somehow uses your system's cache or something, either way, it is an odd bug) host# nslookup archive.ubuntu.com Copy or write down the IP address you get host# vim (or other text editor as root) mnt/etc/hosts Add the line: ip-address-from-above archive.ubuntu.com You can alternatively do this: host# echo ip-address archive.ubuntu.com >> mnt/etc/hosts host# chroot mnt host# apt-get update I suspect that both the 'sudo' package, 'net-tools' and 'dnsutils' are meant to be part of Ubuntu Core.
