dpkg error preventing install or upgrade

[Masterjuggler]

I removed lite-software and the package system repair was able to successfully complete. It did not fix the update errors, and installing lite-software returned the upgrade error.

I was refraining prom posting the full output as you don't have spoiler tags bbcode. Here is the full output:
