could not install initramfs-tools during distribution upgrade

[Dion Curchin]

Binary package hint: update-manager

Was upgrading to Lucid. The distro was an up to date Kubuntu 10.04 with KDE SC 4.5.1

ran kdesudo "do-release-upgrade -m desktop -f kde -d"

The machine is an Athlon 64 with 1.5 Gig ram and a Nvidia 7600GS with the Nvidia Driver 195.36.24

Was upgrading fine until 34% into "Installing the upgrades". Produced a dialog box stating:
  "Could not install 'initramfs-tools'. The upgrade will continue but the 'initramfs-tools' package may not be in a working state....."
    "subprocess installed post-installation script returned error exit status 1"

Allowed install to continue. On completion of installation and updates, upgrade manager again recommended submitting a bug report.

Once upgrade fully complete. Opened terminal and ran "sudo dpkg --configure -a"

The following output was produced.

sudo dpkg --configure -a
