I did apt-get update before typing the command. How can I get binutils? I am using Ubuntu 12.10.

I am following the instruction on https://wiki.ubuntu.com/Toolchain/Crosscompilers/ARMEABIToolchain

I am stuck at the first line.

I did sudo add-apt-repository ppa:germia/archive3 previously, however I got some errors then, I did sudo add-apt-repository --remove ppa:germia/archive3 to undo the setting. I wonder if my problem is related wtih this PPA?
