Title:
  do-release-upgrade to 14.10 fails

Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  Initially, I had third party packages.  I purged them, removed
  /etc/apt/sources.list.d/*, and even purged the system of the
  community-supported apps.  Now the only packages on the system are
  officially supported ones.

  Occasionally, I got errors about a 0xA0 Unicode decode error, which I
  eventually tracked to a completely messed up  /var/lib/update-manager
  /meta-release which was an HTML file.  I deleted it and let the system
  recreate it on a further run of do-release-upgrade.  The new version
  appears to be good.

  $ lsb_release -rd
