I've had this issue before too. Make sure you've updated your server. My understanding is that the -autoupdate option doesn't work on the Linux version of srcds, so you'll need to run the update manually. Any time Valve has come out with an update, I've had to manually update my server even when -autoupdate is in use. It gives me the same error you're getting until I run that manual update.
