[Bug 972044] [NEW] 12.04 beta2 upgrade fails with Unauthenticated packages

[cp]

Public bug reported:

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.

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.
