OK... I'm really new to linux. I have read thread after thread and tried to type the code just the way it is written. I don't know why but none of it works. I have found out if I just download an rpm into my /home/<username>/documents folder all I have to do is right click on the rpm file icon. this pulls up another window and I select install with YAST. Yast does the rest... So can anyone please tell me why that works but typing in the code doesn't?? and also, is there a reason why I shouldn't install that way?? I have tried many times to install a "tar.gz." but no luck.
