Title:
  do-release-upgrade could not calculate the upgrade

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

Bug description:
  do-release-upgrade terminates without upgrading. Message on terminal:

     Could not calculate the upgrade

     An unresolvable problem occurred while calculating the upgrade.

     If none of this applies, then please report this bug using the
  command...(etc)

  It gives no indication what the problem might be or how i can resolve
  it.

  apt.log contains a lot of lines like:

    Setting alsa-base:amd64 NOT as auto-installed (direct Depends of ubuntu-desktop:amd64 which is in APT::Never-MarkAuto-Sections)
    Setting alsa-utils:amd64 NOT as auto-installed (direct Depends of ubuntu-desktop:amd64 which is in APT::Never-MarkAuto-Sections)
    Setting anacron:amd64 NOT as auto-installed (direct Depends of ubuntu-desktop:amd64 which is in APT::Never-MarkAuto-Sections)
    etc.

  But it is not clear how it can be resolved.
