Is a skybox necessary for an underground map?

The title of my post sums up the question, but I'll elaborate as follows. I'm about to get a map ready for alpha testing. It's set in an underground subway station. The map has no leaks, but I keep getting an error relating to skyboxes. I'll paste the error at the end of my post.

I've noticed entirely indoor maps like ctf_turbine still have a kind of vestigial skybox. it seems to help with lighting. My map is lit entirely by indoor light_spots, and I like the feel more than env_light.

Long story short< do I need to add a carefully fitted skybox to the map? there are areas where a ceiling grate might look cool, but I'd rather avoid them if necessary. thanks alot for any input.

Thanks for the help gentleman. I figured there was an obvious answer but I couldnt find one on the forums. Thanks alot.

Well I guess the question wasn't as dumb as I thought. I couldn't find the error in the forums, so I figured it was my long term lack of mapping knowledge that caused it. this is the first map I'd even consider testing, so I never took notice of it if it happened before. thanks alot.
