After using the command at timestamp 6.36, its asking me for username and password of GitHub account related to A cloud guru.
and then it says authentication failed.
Not sure if this helps, but my guess is that GitHub may be case-sensitive, so make sure you enter your command exactly as shown, caps and lower-case exactly.
I also having the same issue
The repository is public and doesn’t require any credential to clone. Which command did you type?
I also having the same issue – this is what I type
$ git clone https://github.com/ACloudGuru/gcg-cloud-engineer.git – Is asking for a Username for https://github.com
