Gitlab推送第一个项目失败，因为无法从远程存储库读取

Question

I was new to Gitlab was trying to push my project from local machine to Gitlab.

Have done the SSH key and followed the instructions at Gitlab. Done the Git global setup. Was trying to add an existing folder , so i followed the instructions listed

cd existing_folder
git init
git remote add origin https://gitlab.com/sss/testnode.git
git add .
git commit -m "Initial commit"
git push -u origin master

but failed at the last step at the git push. The error message was

Tried adding the remote origin, but it was told it already exists. So not sure where it went wrong. Please help, much appreciated :)

Answer 1

Have done the SSH key

The problem is that you have defined your origin as HTTPS, not SSH.

Try:

git remote set-url origin git@gitlab.com:sss/testnode.git

That will override origin URL.

Independently, make sure your SSH key does work and allows GitLab to authenticate you as your GitLab account with:

ssh -T git@gitlab.com

Answer 2

Check out your credentials, if they are invalid, it wont give u to upload changes.

For Windows check this: https://www.digitalcitizen.life/credential-manager-where-windows-stores-passwords-other-login-details

For Linux check this: https://askubuntu.com/questions/30907/password-management-applications (if you do not know how to change credentials via terminal)
