** Description changed:

- Binary package hint: update-manager
+ Because of the overloaded servers update-manager gives a unclear error
+ message that ubuntu-minimal is missing and aborts (doing a proper
+ cleanup and no harm in any way to the system). The error message is
+ problematic because the real problem is that the server in question is
+ so loaded that it does not return useful data (a comination of 111
+ connection refused, 403, 404 was observed).
+ 
+ If you experience the problem, please run "update-manager --proposed (or
+ do-release-upgrade --proposed) to get better error checking and let us
+ know here in the bugreport if it helps getting at least a better error
+ message (we can not do a lot to make the servers less loaded at this
+ point).
+ 
+ TEST CASE (for SRU verification):
+ 1. switcht to es.archive.ubuntu.com 
+ 2. run the upgrade (update-manager or do-release-upgrade)
+ 3. watch it fail with a unclear error message about "ubuntu-minimal missing"
+ 4. run "update-manager --proposed" (or do-release-upgrade --proposed)
+ 5. watch it give a better error message about overloaded servers
