Ubuntu phased updates

If you ever got this message when trying to update the system:

 Die folgenden Pakete sind zurückgehalten worden:
   grub-efi-amd64 grub-efi-amd64-bin grub-efi-amd64-signed

It will either solve by itself after some days, typical pattern for phased updates. Or you can speed up things to get those updates first: Create or edit this file: /etc/apt/apt.conf.d/99-Phased-Updates

APT::Get::Always-Include-Phased-Updates True;

 Die folgenden Pakete werden aktualisiert (Upgrade):
   grub-efi-amd64 grub-efi-amd64-bin grub-efi-amd64-signed
