I believe changing the preseed.cfg file to use an IP address for the archive instead of the domain name will work around this; it's not a good long term solution since it messes up ubuntu's dns load balancing, but if you need to perform an install this might work. I'm in the process of verifying this.
d-i mirror/http/hostname string archive.ubuntu.com to d-i mirror/http/hostname string (looked up ip address) and... thank you all for quickly investigating the issue! :) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to eglibc in Ubuntu. https://bugs.launchpad.net/bugs/1674532 Title: Ubuntu 14.04 broken during PXE boot Status in eglibc package in Ubuntu: Confirmed Bug description: After installing the libc6_2.19-0ubuntu6.10_amd64_udeb package during the automated install of ubuntu 14.04.5, the system was suddenly unable to resolve hostnames via dns. Installing -0ubuntu6.9 resolved the issue. Reinstalling -ubuntu6.10 broke the system again. I note that -ubuntu6.10 was recently added to the archive. I am currently unable to install Ubuntu 14.04.5.
