Brad, I need some clarification on the apport-collect script. The curtin
environment is a very limited installation environment and when I ran
apport-collect, it was attempting to open a socket but never returned.
AFAICT, it needs to open a browser to allow user to authenticate through
a browser, but I don't see a way for me to do it that way since there's
no browser. Is it possible for the tool to collect this data offline
then use the apport-collect to post the data from another system from
which I can authenticate from? If so, can you please share the steps?

Seth, we haven't recreated this without MAAS but we think that this
should re-creatable in any environment with an overlay root... You could
try with a LiveCD for example. Once inside the environment, then you
would verify content of /tmp then run "sudo apt-get update && sudo apt-
get install libc6" assuming that the libc6 version in the archive is
newer. If the content of /tmp is empty, then issue was successfully
recreated.

Title:
  installing or upgrading libc6 in Trusty removes all content from /tmp
  directory

Status in eglibc package in Ubuntu:
  Invalid
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  We are seeing an issue with installation of dkms package during a
  curtin installation which ends up with /tmp directory being wiped
  clean. This is very bad for curtin as it saves critical installation
  files in /tmp.

  It turns out that it's the of upgrading libc6, which is triggered as a
  result of installing dependencies, that removes content of /tmp. For
  example, installation of gcc results in the same result since it ends
  up with libc6 being upgraded. The only way that this won't be
  recreated is if the latest libc6 is already installed.

  This problem does not exist in precise. It can also be recreated by
  installing the .deb file for any version in trusty including 2.17.
