This looks like a reasonable workaround, thank you. |

@Michagogo You're right (at least for my setup, which is an Ubuntu 12.04 container running inside a 14.04 host). I somehow missed that it was being newly installed... however the hold is preventing its installation. Does this work for you? |

Well, assuming it does work, then that's great (at least until something else goes wrong). I just can't test it right now, because I've temporarily worked around the issue by recreating the VM from scratch. |

(I don't really know all that much about apt/dpkg, so I don't actually know what a "hold" is, etc...) |
This PR attempts to close #86.
It simply places a dpkg hold on grub-pc in
upgrade-system.shto prevent itsupgradeinstallation. This should be a fairly conservative approach.Unfortunately, when
grab-packages.shtries to download grub-pc viaapt-get install -q --reinstall -y -d grub-pc,apt-getfails due to the hold. It could remove the hold first(and that works today), but there's no guarantee that old packages will remain available in the archive, so the safer approach was to prevent any held packages from being downloaded., and given @Michagogo's correction below this would probably be just as good a solution, but instead it filters out grub-pc from the downloads. As it is now, this changes the manifest (for better or worse) to reflect that grub-pc isn't installed.
