[Bug 878062] Re: Installer removes packages, but fails to update package database

[Troy Thompson]

I had the exact same results as Marshall and tried several of the things
he did.  I had the grub error as expected and my machine also has SSD
and was installing from a flash drive.  I was installing the 64bit
version of Ubuntu.

Thanks to his additional feedback I was able to solve the problem in the
same method he did.  I was able to duplicate this error sequence twice
due to unplanned fresh installs recently.

Title:
  Installer removes packages, but fails to update package database

Status in “ubiquity” package in Ubuntu:
  Triaged

Bug description:
  There is a set of packages that are installed on the livecd that get
  removed during installation.  Sometimes the package database fails to
  be updated to reflect that the packages were removed, so while the
  files are gone, the package database still shows the package as being
  installed.

  This problem can manifest itself when users install gparted, which
  depends on libgtkmm-2.4.so.1.  The package database things this
  library is already installed, but in fact, the files were removed
  during installation, so gparted can not load the library.  Other
  packages have been affected as well, though the problem is difficult
  to reproduce.  It may require getting an error during the grub
  installation phase.
