Title:
  USC allows a package installation to uninstall vital packages

Status in “software-center” package in Ubuntu:
  Confirmed

Bug description:
  I downloaded steam_latest.deb from steampowered.com, saved it, double
  clicked on it, and Software Center launched.  It brought up the deb
  information page, I clicked Install, and Software Center proceeded to
  remove literally about half of the installed pacakges on my system
  (about 400), including things like unity, ubuntu-desktop, and,
  ironically, software-center itself.  It eventually errored out (see
  attached log).

  Using /var/log/apt/history.log, I was able to restore the system's
  packages to their previous state, but Software Center shouldn't have
  allowed this to happen (whether or not the third-party .deb was
  actually at fault).

  NB: To correct the apt error, I did "apt-get -f install".  Then, after
  I apt-get installed the packages which were removed, steam was still
  installed, so it wasn't a dependency error which caused the packages
  to be removed.  I have no idea why it actually happened.
