[Bug 927993] Re: distribution upgrade from lucid to precise failed with : package dpkg is already installed and configured

[Michael Vogt]

When comparing the two logs (one with debug and one without) I noticed that they start to diverge when the xserver bits
are removed. Its not quite clear yet why, I run with -o Debug::pkgDPkgProgressReporting next

The dry-run has:
/usr/bin/dpkg --force-overwrite --status-fd 96 --force-depends --force-remove-essential --remove xserver-xorg-video-tseng ^M^M
/usr/bin/dpkg --force-overwrite --status-fd 98 --unpack --auto-deconfigure /var/cache/apt/archives/xserver-xorg-video-siliconmotion_1%3a1.7.5-1build2_amd64.deb /var/cache/apt/archives/xserver-xorg-video-ati_1%3a6.14.99~git20111219.aacbd629-0ubuntu2_amd64.deb ^M^M
/usr/bin/dpkg --force-overwrite --status-fd 100 --force-depends --force-remove-essential --remove xserver-xorg-video-nv ^M^M


And the real one:
[pid 16170] execve("/usr/bin/dpkg", ["/usr/bin/dpkg", "--force-overwrite", "--status-fd", "30", "--force-depends", "--force-remove-essential", "--remove", "xserver-xorg-video-tseng", "xserver-xorg-video-nv", "xserver-xorg-video-chips", "xserver-xorg-video-i128", "xserver-xorg-video-ark", "xserver-xorg-video-rendition", "xserver-xorg-video-s3virge", "xserver-xorg-video-voodoo", "xserver-xorg-video-apm", "xserver-xorg-video-v4l"], [/* 31 vars */]) = 0

  -rw------- 1 root   root   150K 2012-02-06 13:34 _usr_sbin_cron.0.crash
