I run ubuntu linux and I have just bought a new ipod touch

You need itunes to set it up, which is, as usual, only available for Windows and mac (stupid apple for forgetting linux!!!).

How can I set up my ipod?

Thanks, Calum

this is a long route but might work!
you could install 'wine' (windows emulator) into linux and then try itunes in 'wine', you may have to install a version of windows as well!

you could also try amarok, it's available for both the gnome and kde desktop environment.
