I just had a daily update in Ubuntu 12.04, and during the update, ir gace an error saying it couldnt install the update and because of this you might not be able to boot from grub.......once I carried on, and rebooted, the grub appeared, you hit enter and that error appears

One thing I forgot to mention, once you hit any key, it does boot up......

Was the error the one given in bug #972250?

Status changed to 'Confirmed' because the bug affects multiple users.

I get this message at boot after the most recent grub update. I didn't get it before and didn't see any errors when updating grub. (It did ask and overwrite my /etc/default/grub which I had modified.)

Te exact error message is the one in the bug title. I don't see any grub related errors in /var/log/apt/term.log either.

sudo dpkg-reconfigure grub-pc

helped for me.

I got the above when updating today along with a screen warning me it had failed to update grub. Will reboot later and hopefully confirm it still boots.

This appears to be the same as bug 972250, and should likewise be fixed by 1.99-21ubuntu1.
