Title:
  do-release-upgrade fails to configure properly Grub from Precise to
  Quantal.

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Expired

Bug description:
  Hi,

  I'm not entirely sure of where I should post this.  Please redirect this if I did wrong ☺
  As I was encountering a lot of problem with Precise, I thought it would be a good idea to send bug reports from Quantal rather than from Precise.  I thus decided to upgrade to Quantal.  I've got some minor problems, which I will explain in details after this first description of what did happened after the upgrading.

  “do-release-upgrade” seemed to have work well as it suggested me to restart my computer, with no obvious error shown.  So I did as it suggested me to do.
  Once I restarted, I only got a message from Grub stating this:
  error: file not found.
  grub rescue>
  Without any additional information (by the way, stating *which* file has not been found would be a non-neglectable improvement of Grub ☺), I tried some things, such as “help“, “reboot” or other classical command.  “ls” returns me a list of partitions, but I do not know what to do with those…  I'm searching on my live-CD ☺
  I do not know what happened, but I hope such error won't happen the day of the official release!

  By the way, my live-CD seems to work well:  if you want me to upload
  any useful file, just ask!

  Some problem I encountered meanwhile that maybe could help (or that should be reported to another software):
  → “upgrade-manager -d” refused to upgrade to Quantal because of “unknown error”.  It suggest to send bug report, so I did.
  → Maybe this is linked with the last one, but I encountered some problem of space in my “/” partition.  I thus removed some of my space-consuming software to be able to upgrade with “do-release-upgrade”
  → I got a lot of problem with Gnome-shell these last months.  Those problems seemed to be caused by contradictory old configuration files (my system fonts keeps changing, my mouse design too, and so did my keyboard mapping.  Each time such a “change” happened, the system froze for one or two seconds), maybe this is linked with this problem of upgrade…  Anyway, a program that is not able to choose between two configuration file, should choose one (at random if needed) for the entire session and do not change its mind.

  I'm working on fixing my computer on this little live-CD, but if
  meanwhile you need any further information, just ask:  it would be a
  shame that such a bug appears at the final release!

  Best,
  Martin.
