OK folks, I think I really blew it. I was trying to install a game from the Hoary distro (I'm using Warty) and it needed a newer version of a particular lib than the one I had. So after trying a bunch of other things, I issued this command:

sudo apt-get -t Hoary upgrade libexpat1

(libexpat1 is the library I wanted to upgrade).

And suddenly, bam, a TON of stuff got upgraded:

The following packages have been kept back:

I blissfully hit Y at the prompt without really thinking, then watched all this stuff scroll by in a panic.

So do I now have a system with one foot in the Warty world and one foot in the Hoary world? What's going to happen if I reboot? Will my system come back?


Clearly no one should be giving this linux newbie power-tools to play with.
