[Bug 379789] Re: Ubuntu 9.04, live-install rescue/enable=true Fails

[Phillip Susi]

That option is meant to be entered after choosing the option to append
additional arguments to the kernel command line, and also is for the
server installer not the desktop.

Title:
  Ubuntu 9.04, live-install rescue/enable=true Fails

Status in “ubiquity” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: live-installer

  Got a display issue with Nvidia driver, and in trying to follow
  instructions, the system suddenly reverted to low resolution mode on
  bootup, and nothing works to fix it.  Not that I really know what to
  do, which is why it is such a problem.  Not even sure how to mount
  another partition with a working install so that I can compare
  details.

  Anyway, there is very little said about how to rescue a broken
  installation, except that it should be possible.  I refer to
  https://help.ubuntu.com/9.04/installation-guide/i386/rescue.html in
  this regard.

  AS far as I can tell at this point, there are only two options for
  booting from a live CD with Ubuntu 9.04 on it.  First you have to get
  to a text-base mode, and the method for doing that is not obvious.  I
  found it as toggling down to Install Ubuntu as my choice option from
  the start-up screen, then hitting the Esc key, which offered me a
  chance to exit the GUI mode and go to text mode instead.  So i did
  that.

  next, I had a black screen with this showing:

  Boot:

  Boot what?  No choices offered.  I tried several names that I could
  think of, but the only response was that it could not find an image
  with that name.  I did not know what to do to get a list of available
  images.  Finally, in desperation, I typed help, and that worked.  I
  suddenly had a help screen, similar to but not the same as the one in
  the GUI.  I tried F1 for more help, and got a differentl list of
  possible options.  There was one for dealing with a broken system, but
  you pick that, you only got told that it was do-able, but not how.
  However, I had the info from the link above (only obtained with the
  help of another PC with online access), so I decided to try both the
  boot and the rescue/enable=true options mentioned.

  Boot was not valid.  No image by that name.  Rescue/enable=true not
  valid either, as no image callded rescue was found either.  Somehow I
  stumbled on the fact that there were just three images identified, one
  called live, the second called live-install, and the other something
  else, but it only tested the PC memory.  I've been through so much
  lately that some details escape me.

  Anyway I decided to give live-install rescue/enable=true a chance, and
  it seemed to work.  Up to the point of where the partitioner got
  called in.  Instead of seeing a different drive view where my choices
  were which partition to rescue, and no notice of the fact that this
  was just a rescue effort and my data would remain intact (as promised
  in the link above), I only had the choices of which method to do a
  fresh install again.

   Now I know that if you pick the manual mode, then hand select the
  partition to be used as root (/) but not to format it (leave that box
  unchecked), then you will we warned (advised maybe?) that only the
  system files will be replaced.  Well, that could work, but I've
  already found (and reported in another bug report) that the
  partitioner screens are so stretched left and right, that the key box
  of Forward goes clear off screen.  So you can still use Alt+F to go up
  to the point of actually performing the install, but no further.

  I guess I will go back and try with the boot option of live
  rescue/enable=true and see if it flies, but my expectations are not
  that great, in fact lowered simply because the live approch already
  assures someone that no changes will take place with the hard drive
  contents.  Sure looks like the ability to Rescue a Broken System is
  nothing but a myth at this point.  You have no plan in place to do so,
  none that any novice or semi-competent person can fathom or make use
  of.

  I would certainly call that a bug worth reporting.  And it also points
  up the severity of the previously reported bug as well, because now it
  hinders efforts to restore a damaged system.
