grub2 2.00-18ubuntu2 fails to install with "grub-probe: error: failed to get canonica

[paul_in_london]

I've been bitten by this. There's already a bug report:

https://bugs.launchpad.net/ubuntu/+s...2/+bug/1223959

More specifically in my case it was the update to grub-pc. I don't actually have grub2 installed. It seems to be a meta-package. I haven't needed it anyway.

That's odd I show about the same thing exept the red.

Like me, you have gub-pc and (presumably) grub-common installed.

I think maybe you meant to post the output of:

paul@lubuntu-64:~$ apt-cache policy grub2
grub2:
  Installed: (none)

Anyway, a fix is apparently in the pipeline.

Just a quick one-liner as a workaround for now:

sudo apt-get install grub-common=2.00-18ubuntu1 grub-pc=2.00-18ubuntu1 grub-pc-bin=2.00-18ubuntu1 grub2-common=2.00-18ubuntu1

You are right! grub2 is not installed.

I try to keep my grub installed on a healthy Ubuntu like 13.04 because I hate seeing grub rescue and believe me I have seen it a "couple" of times.
Another reason I like to have more than one install. Today's updates borked my flashback session - no panels and weird errors.

Hopefully this too will be fixed.

[paul_in_london]

Fixed now with latest updates.
