There are a lot of files there, but none that start with grub. I also searched /var from the command line, and I got the following: locate grub-pc /usr/share/bug/grub-pc /usr/share/bug/grub-pc-bin /usr/share/bug/grub-pc/presubj /usr/share/bug/grub-pc/script /usr/share/bug/grub-pc-bin/presubj /usr/share/bug/grub-pc-bin/script /usr/share/doc/grub-pc /usr/share/doc/grub-pc-bin /usr/share/lintian/overrides/grub-pc-bin /var/crash/grub-pc.0.crash /var/lib/dpkg/info/grub-pc-bin.list /var/lib/dpkg/info/grub-pc-bin.md5sums /var/lib/dpkg/info/grub-pc.config /var/lib/dpkg/info/grub-pc.list /var/lib/dpkg/info/grub-pc.md5sums /var/lib/dpkg/info/grub-pc.postinst /var/lib/dpkg/info/grub-pc.postrm /var/lib/dpkg/info/grub-pc.preinst /var/lib/dpkg/info/grub-pc.prerm /var/lib/dpkg/info/grub-pc.templates The file /var/crash/grub-pc.0.crash is obviously interesting, so I opened it in mousepad. It contains hundreds of pages of grub-pc errors, and the one at the very top of the page was when I installed a program 'sound converter' a few weeks ago, and at the end of the installation there was the error message 'unable to configure grub-pc.' Well, I've seen hundreds of those, so there's no point in wading through the file. Mind you, there might be something more interesting, but I doubt I'd accomplish much without knowing what to do a text search on. And all I searched was /var. If there are other places where we might find clues let me know. Or if any of the other files above are interesting I can look at them.
