I'm kinda stuck

I'm using fremantle 1.3
n900
maemo 5
Version: 20.2010.36-2

I've tried sudo apt-get install git-core

it replies: "Couldn't find package git-core"

I've also tried downloading git-core from these repos
/extras-devel/pool/fremantle-1.3/free/g/git/
and
/extras-devel/pool/fremantle-1.3/free/g/git-core/
and when I try to install it says:

"Unable to install "git-core"
Incompatiable application package"

What am I doing wrong? I'm stuck!
