How do I update git to the latest version?

Question

I'm Japanese boy.

I am using git version 2.1.4 on GCE.

$ git --version
git version 2.1.4

I'd like to update to the latest version, but it was not updated when I executed the following command.

sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get upgrade

Is my way wrong?

---

After that,I tried the following but it got an error.

sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update

The following error has occurred.

W: ppa.launchpad.net/git-core/candidate/ubuntu/dists/jessie/mai‌​n/… 404 Not Found
W: ppa.launchpad.net/git-core/ppa/ubuntu/dists/jessie/main/… 404 Not Found

I found out how to fix with ubuntu, but do you know how to fix GCE (debian)?
