[Git] Error: remote rejected (permission denied)

The error pop up When I pushed the changes on a new branch for the first time.

 ! [remote rejected]     oscar-next -> oscar-next (permission denied)
error: failed to push some refs to 'https://github.com/oscarzhou/portainer.git'

The solution is to update the git config like below

git config --local --list
# old config
remote.origin.url=https://github.com/oscarzhou/bar.git
# update new config with
git config remote.origin.url https://foo%40gmail.com@github.com/oscarzhou/bar.git

After that, we can run git push --set-upstream origin <branch_name>
