[Bug 1674532] Re: glibc update caused NSS ABI break

[thecyborgus]

I'm still seeing this on Ubuntu 16.04 connecting to Amazon RDS as well.

Apache service reloads had temporarily resolved it, but I got a huge
rash of these again across all of my servers during the Unattended
installs again last night.

I rebooted after the error cropped up and it worked for about 8 or 9
hours before it happened again on the same servers.

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.
