Comment 1 for bug 1674532

"Suddenly" refers to the log in which it is happily downloading stuff from the archive and after successfully downloading and installing the libc6_2.19-0ubuntu6.10 package it is unable to download the next package because it can no longer resolve the archive.ubuntu.com name that it had been resolving prior to the installation of that libc6 library. I unfortunately don't know how to get logs off the system to send in :(
