[ubuntu] Update-grub says my /usr is broken?

[bubba_169]

Im confused and google is turning out nothing for me? After updating to a newer kernel, 2.6.27-11 from 2.6.27-7, I noticed it wasn't showing up in grub. I tried running update-grub and the exact error message I get is:

$ sudo update-grub
Your /usr is broken, please fix it before call this wrapper!

Any ideas?

Yeah, just figured it out. You need to do the following:

chmod 744 /usr/sbin/update-grub

The problem is that when you call "update-grub" it runs the script /sbin/update-grub (not in /usr), this file checks a couple of things, one has to do with your kernel conf file stuff (not real sure what it is about) and the other makes sure that /usr/sbin/update-grub exists and is executable. Right now, /usr/sbin/update-grub is not executable.

So, run the chmod and then "sudo update-grub" and it will work.

In my case the file /usr/sbin/update-grub is missing..
What should i do?

Reinstall grub-gfxboot package. It is the one that has update-grub in it.

There is no package with name grub-gfxboot, but there's a gfxboot package which I already installed. Still, no /usr/sbin/update-grub but there's a /sbin/update-grub.

$sudo update-grub
Your /usr is broken, please fix it before call this wrapper!

Well the correct package was grub-pc, which installed /usr/sbin/update-grub.

The package is installed by default, but it got removed for me when I had installed a package 'grub-choose-default'.

[breusshe]

Oh, sorry for pointing you to the wrong package. Glad you got it going again.

The funny thing is, installing 'grub-pc' to get back /usr/sbin/update-grub removed the package 'grub', which contained /sbin/update-grub, which gave the above error message in the first place
