I upgraded some packages earlier (including a kernel) and received an odd error from grub (version\u00a01.99-21ubuntu3.9)<\/p>\n
$ sudo grub-install --recheck \/dev\/sda\r\n \/usr\/sbin\/grub-probe: error: not a directory.\r\n Auto-detection of a filesystem of \/dev\/sdb1 failed.\r\n Try with --recheck.\r\n If the problem persists please report this together with the output of \"\/usr\/sbin\/grub-probe --device-map=\"\/boot\/grub\/device.map\" --target=fs -v \/boot\/grub\" to <bug-grub@gnu.org><\/pre>\nI couldn't complete the configuration of the updates that I had downloaded, and worse the machine was probably now unbootable. Poking around a bit, I find that the error reported by grub-probe could be reproduced with:<\/p>\n
$ sudo grub-probe -d \/dev\/sdb1 --target=fs_uuid\r\ngrub-probe: error: not a directory.<\/pre>\nI didn't know where to go from here so the first thing I tried was to purge grub and reinstall it.<\/p>\n
sudo apt-get purge grub*\r\n\r\nsudo apt-get install grub-pc<\/pre>\nDidn't make any difference, so the next thing I tried was to downgrade to an earlier version of grub (1.99-21ubuntu3).<\/p>\n
sudo apt-get purge grub*\r\n\r\nsudo apt-get install grub-pc=1.99-21ubuntu3 grub2-common=1.99-21ubuntu3 grub-pc-bin=1.99-21ubuntu3 grub-common=1.99-21ubuntu3<\/pre>\nUnfortunately this made no difference either. So the next thing I tried was to install the version of grub from Ubuntu 12.10. There were some dependency conflicts which I had to manually fix as you can see here:<\/p>\n
sudo apt-get remove apport-hooks-medibuntu apport-gtk apport\r\n\r\nsudo dpkg -i liblzma5_5.1.1alpha+20120614-1_amd64.deb\u00a0grub2-common_2.00-7ubuntu11_amd64.deb \u00a0grub-common_2.00-7ubuntu11_amd64.deb \u00a0grub-gfxpayload-lists_0.6_amd64.deb \u00a0grub-pc_2.00-7ubuntu11_amd64.deb \u00a0grub-pc-bin_2.00-7ubuntu11_amd64.deb<\/pre>\nFinally, grub installed ok!
