[Bug 1513232] Re: do-release-upgrade no longer works from lucid to precise

[Nowell Morris]

Confirmed comment #3 fixed my issue of upgrading from 10.04 to 12.04.  I
did have a number of 404 errors in the output, but the update manager
seemed to have retrieved all that was necessary to do the upgrade.  I
had added the AllowUnauthenticated=true statement to /etc/update-manager
/release-upgrades because there was no file in release-upgrades.d/ but
doing so on its own, or before making the manual changes in post #3,
would not work by itself.  It seems that #3 would be sufficient without
adding the AllowUna.. to any file anyways.

Bug description:
  When trying to run do-release-upgrade to go from Lucid to Precise, the
  upgrade fails with :

  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. 

  accountsservice ...

  Workaround is to add the following statement in /etc/update-manager/release-upgrades.d/unauth.cfg :
  [Distro]
  AllowUnauthenticated=yes
