Hi all,

i m trying to upgrade my linux from fc4 to fc5 using DVD version of fc5 installation package.

But everytime that i try to install it (new install or upgrading my existing FC4), it gives this error :
"...
File "/usr/lib/anaconda/fsset.py", line 1050, in mount
raise SystemError(errNum, errMsg)
UnboundLocalError: local variable 'errNum' referenced before assignment
..."

i thought that this problem is a DVD reading/writing problem. and i try both DVD media(+/-). nothing changed. (DVD Mediacheck is OK)

does anyone have an idea about that?

thanks in advance.

PS1. we succeeded to install it on another machine. (???)
PS2. i tried to install it using text mode. it gives a similar error as before. only difference is filename (fsset.py) --> (text.py).
