Update git because of CVE-2022-23521

[Jan Bauer]

Please provide the latest git for Ubuntu LTS (18, 20 and 22)

The current version appears to be 2.39.1. The versions available from apt seem to be pretty old. We still have some systems with Ubuntu 18 LTS, and I see 2.17.1 there after running sudo apt update && sudo apt upgrade -y

Status changed to 'Confirmed' because the bug affects multiple users.

It appears that Canonical does not want to provide a fixed version.

So I decided to change the git source repo, and get a fresh git with:

sudo add-apt-repository ppa:git-core/ppa
sudo apt update
sudo apt install git -y

now check the version with: git --version

and it has 2.39.2, works on Ubuntu 18.04 without issues.

Conclusion: there is no reason to stick at the old git 2.17.1 on that distro.
