Hello dear members!

I just got a 2nd rig dedicated for mining and i thought using Ubuntu (no experience with Linux what so ever).
I have follow this thread (https://bitcointalk.org/index.php?topic=189499.0) and having problems.

Im right at this step:

The exact line that the problems occur are:
When i type that line in terminal i get this error:
"Cannot open: No such file or directory
tar: Error is not recoverable: exiting now"

I have downloaded the APP SDK v2.8 Inx64.tgz and have tried both letting the .tgz be located where it is placed after downloading and it also tried to make a folder named miner in the home location ( /home/miner/ )
I get the same error with both methods, so i would need some help from someone familiar with Linux (Ubuntu 12-04 > XUbuntu).


Would really appreciate if someone could help me out!
Cheers!
