Comment 4 for bug 572054

The problem was with dependencies while installing the package, not with running the kernel, so I cannot see why testing an upstream kernel packaged the same way should be interesting.

These are the relevant lines found in /var/log/apt/term.log

Could not find postinst hook script [update-grub].
Looked in: '/bin', '/sbin', '/usr/bin', '/usr/sbin'

I now assume that the problem has something to do with the fact that I had tried to move from grub to grub-pc some months ago, but eventually removed (uninstalled) grub-pc again.

These are of course quite singular circumstances so feel free to just discard this bug report.
