"Removing ubuntu-desktop ..."
This at least should have caused USC to cancel the installation before
it even began. I have a design for this situation in Software Updater
<https://wiki.ubuntu.com/SoftwareUpdates#uninstallable>, but it hadn't
occurred to me that the same thing could happen with USC.
If you don't mind, I'll focus this bug report on the issue of installing
anything that would remove vital components. Problems with the Steam
package in particular are outside the control of Ubuntu developers.
** Summary changed:
- Software Center removed half my system
+ USC allows a package installation to uninstall vital packages
** Changed in: software-center (Ubuntu)
Status: New => Confirmed
** Changed in: software-center (Ubuntu)

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.
