Public bug reported: 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.
