I read about a security flaw in Git, which was fixed in version 2.2.1. I currently have Git 2.1.0 on my system (Ubuntu 14.10), and tried to reinstall it with apt. However, apt told me that I currently have the latest version.
The Git website does not have prebuilt versions for Linux. They say that you can install it with package managers. Without building from source, how would I install the latest version of Git?
