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

[Brian Murray]

Bug 1538299 is about packages being downgraded being disguised as
unauthenticated ones. However, if I recall Louis's bug correctly nearly
every package was unauthenticated which would be a surprising number of
packages in L > P.

Title:
  do-release-upgrade no longer works from lucid to precise

Status in update-manager package in Ubuntu:
  Confirmed
Status in update-manager source package in Precise:
  Confirmed

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
