- = User Stories = 
-  * Jim is using JuJu, and adds a node.  He does not want to see apt fail due to a race condition.
-  * Marley is using the Ubuntu installer for network based installs against a local mirror that is updated from a remote mirror.  He does not want installs to fail due to the mirror being updated.
-  * Sally wants to use a http proxy to cache deb downloads and does not want to be vulnerable to caching mismatched files that would cause apt failures.

  None
  
  = Test Plans =
  Test will be conducted in 2 ways:
-  a.) implied test: much of our automated infrastructure relies on apt and previously failed quite commonly due to apt.  These errors should be erased.
-  b.) explicit test: we should ideally have some canary that would ensure our public mirrors do not fail. One example starting point is [1]

  = Release Note =
  Ubuntu's public mirrors now contain an improved archive format.  Coupled with updates to apt transient apt-update errors are a thing of the past.
