Ubuntu 9.10 installation

I get an error trying to unpack the source. I'm reading the wiki, and trying, but this is what I am inputting and getting in return.

input: tar jxvf vdrift-2009-06-15-src.tar.bz2
tar: vdrift-2009-06-15-src.tar.bz2: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
