Install Git on Ubuntu 24.04 and Configure for Verified Commits in GitHub
Git is an open source distributed version control system that is the most widely used by software developers today. Its decentralized nature makes it essentially censorship-proof and very robust against accidental deletion or permanent loss of work. Even if somebody accidentally deletes the remote repository entirely, each member of the team has a full version of the project and can just create another one.
In this video, we install Git on a mostly fresh copy of Ubuntu 24.04 (with Visual Studio Code installed). Because we want to use Git with GitHub and get that sweet-sweet Verified tag on our commits, we install git along with the dependencies needed for git-credential-libsecret:
`sudo apt install make gcc git libsecret-1-0 libsecret-1-dev libglib2.0-dev`
After installing Git, we do some basic global configuration, (including enabling rerere, you'll thank me later), create a GPG signing key, upload that signing key to GitHub, and create a GitHub access token with repo access.
We use git-credential-libsecret to improve security so we don't have the access token stored in plain text somewhere on the hard drive.
This video covers:
00:00:00 Introduction and overview of Git
00:03:41 Install Git along with libsecret dependencies
00:04:53 Post install verification and initial global config setup
00:07:50 Create a basic local repo to make sure local committing works
00:10:40 Set up GPG key so commits can be signed.
00:16:04 Add the GPG key to the GitHub account
00:18:11 Configure git-credential-libsecret as the credential helper
00:19:56 Generate a GitHub access token
00:22:33 Clone a remote repo and create a commit on a throwaway branch to test the token and signature
00:25:20 Copy the generated access token and use it to authenticate when pushing
00:26:11 Look in GitHub to ensure the commit shows as verified and then remove the throwaway branch from the remote.
00:27:43 Review the option to always sign commits `git config [--global] commit.gpgsign true`
