The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName

As outlined here, there are a couple of situations where you need to authenticate with GitHub by using an Acces Token:-

1. If you have Two-Factor Authentication (2FA) enabled.
2. You are accessing an organisations protected content using SAML Single-Sign On (SSO).

Create an Access Token

In your GitHub account, go to Settings / Developer settings / Personal access tokens and select Generate New Token. Make a note of the token somewhere safe since this is the only chance you get to see it.

Add the token to your local OSX Key Chain
