Title:
  Unable to automatically remove packages that become unused in
  conjunction with updating by other software

Status in unattended-upgrades package in Ubuntu:
  Confirmed

Bug description:
  When using default settings for unattended-upgrades i.e.
  Unattended-Upgrade::Remove-Unused-Dependencies "false"; 
  # default "false"
  Unattended-Upgrade::Remove-New-Unused-Dependencies "true"; 
  # default "true"
  in configuration file /etc/apt/apt.conf.d/50unattended-upgrades,
  U-U is unable to remove packages that become unused in conjunction with updating by other software such as update-manager or apt full-upgrade. This is because U-U compares the list of unneeded packages before and after it upgrades packages to detect which packages are new unused ones.
