Garrys ModWorkshop error

[Sonicnine1]

when i set up the workshop like it says on the garrys mod wiki,it says download failed. i think it has to do with this error

Code:

Initializing Steam libraries for secure Internet server
[S_API FAIL] SteamAPI_Init() failed; SteamAPI_IsSteamRunning() failed.
dlopen failed trying to load:
/home/administrator/.steam/sdk32/libsteam.so
