Title:
  12.04 beta2 upgrade fails with Unauthenticated packages

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  Tried upgrading with do-release-upgrade -d and update-manager -d and I
  get an error about authenticating some packages, but it appears like
  it is the whole list of Packages.  This is an old laptop running 11.10
  lubuntu.  /var/log/dist-upgrade/main.log attached.  I am using approx
  on a 11.10 machine to lessen our downloading.

  Calculating the changes

  Error authenticating some packages

  It was not possible to authenticate some packages. This may be a 
  transient network problem. You may want to try again later. See below 
  for a list of unauthenticated packages. 

  
  Once I changed the sources.list to not use the approx proxy, it appears to be working.
