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.
