I read through the other "Rust setup" thread but nobody seemed to be having the issue I'm having so I thought it'd be better to make my own.
I'm using a VDS w/ Ubuntu 12.04-LTS.
I am pretty new to linux so this could be something I'm doing incorrectly, but I'm not sure. I got my TeamSpeak server working properly, so I must at least somewhat know what I'm doing

I added a user "steam" and followed Valve's instructions on downloading SteamCMD (super simple)
I then ran steamcmd (./steamcmd.sh), logged in as an anonymous user (login anonymous), and set my install directory (force_install_dir PATH:\SteamCMD\rust_server\ ... this is probably the part I screwed up on, but I'm not sure.)
Now I tried downloading the rust dedicated server
app_update 258550 -beta development validate
and I get this screen

nothing actually downloads, it just immediately displays that my server has been updated successfully.
ANY help would be appreciated! Thanks in advance!
