I am having the same problem since yesterdays updates. Running Kubuntu 11.04 64-bit with btrfs root filesystem. After safe-upgrade I get the follwoing:
$ sudo grub-install /dev/sda /usr/sbin/grub-probe: error: unknown filesystem. Auto-detection of a filesystem of /dev/sda1 failed. Please report this together with the output of "/usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs -v /boot/grub" to <[email protected]> Please inform if there is anything I can do to help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/732149 Title: [natty] btrfs "grub-probe: error: unknown filesystem" -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
