git cant authentication

I'm a developer that has switched to ubuntu and I can't get git to work. I have logged in to git but I still get

> git push origin main:main
remote: No anonymous write access.
fatal: Authentication failed for '

when I try to update the code on GitHub from what's on my PC I'm running

• Ubuntu: 20.04
• git: 2.25.1
• visual studio code: 1.62.2

Run

git config --global user.name "your_username"

This will set your user.name for git.
