I've installed steam but it's refusing to launch. It shows an update screen and then nothing. I've noticed a couple errors while starting with a terminal but I have no idea what they mean or how to fix them. Here's the log:

Looks like steam didn't shutdown cleanly, scheduling immediate update check
