[ubuntu] How can I install GParted on Ubuntu 10.10 PPC

Hello
I have just installed Ubuntu 10.10 PPC on my Mac mini G4 and everything works fine except that I cannot install a simple application called "GParted" on Synaptic Package Manager. I guess I need to add some Repsitory path to the Synaptic and I have tried adding one or two, but they failed with "cannot find/download from the respository" or something like that.

I'd like to learn

if there's a working repository for the Ubuntu 10.10 PPC
if there's way to install GParted directly from Ubuntu 10.10 PPC DVD (GParted is included when I run it as live DVD)

Thanks.
