[orca-list] can't set up the build environment for Orca on Ubuntu

["Mohammed Al-shar'" <mohammed atexplorer com>]

hi listers.

I am back now, after I got a new machine dedicated for ubuntu. I installed 
ubuntu feisty (the dvd version) and it all went smoothly. I would like to 
report that that system boots very fast, even faster than xp.

anyway, my problem is when I issue "sudo apt-get build-dep gnome-orca" it 
tells me:
e: could not open file 
/var/lib/apt/lists/jo.archive.ubuntu.com_ubuntu_dists_feisty_universe_fource_Fources 
 - open (2 no such file or directory)

what do you think is going wrong? it happens with the dvd in the drive or 
not in it, no difference. note also that pinging any internet url will work, 
even if I do "ping ubuntu.com".

thanks alot.
