+ = 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.
+ 
+ = Assumptions =
+ 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 =
