[Bug 1039997] Re: package grub-pc 1.99-21ubuntu3.1 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 127

[Yannick Chasse]

Hi Brian, this is the first time I use the launchpad and since only 1
person is affected, and I am having the issue I guess that would be
me...

If this is the case you can close this issue because you were absolutely
right. I had modified the grub file to fix an SD card reader issue.

Long story short you were absolutely right, I guess I still have tons to
learn.

Many regards,
Yannick C.

Bug description:
  My computer is running Precise downloaded from image on DVD. .  It was
  ok for afew months but now it keeps keeps crashing.  It also maxes out
  apport error reporting .   I have turned off the native RAID in my
  Dell's BIOS to simplify matters but if any thing it seems to have made
  things worse.   I've reinstalled several times but the problems are
  unresolved.

  Still on linux generic kernel 3.20.23.  Been trying to insatall linux-
  image 3.20.0.27, 3.20.29, 3.20.30 using dowload manager, Synaptic and
  boot up recovery mode. They have unmet dependencies which cannot be
  resolved.

  The package grub-pc 1.99-21 ubuntu 3.1 failed to install upgrade etc. in the summary is but one of many errors.   Error messages include:
  "The following packages have unmet dependencies: linux-image-generic (=3.20.30.32) but 3.20.29 is - installed";
   "error processing linux-image-generic (--configure): dependency problems - leaving unconfigured";
  " errors were encountered while processing linux-image 3.2.0 - 27, 29, 30";
  "upgrade: linux-generic linux-image--generic setting up" followed by failure messages;
  "sub-process /usr/bin/dpkg returned error code (1.)";
  Error code 127 also flashed past on many occasions.
