Why git@github.com: Permission denied (publickey) in windows?

Question

I have simply created a repository in github. Using the commands I am trying to upload a project to my new repository. But giving me errors after this command:

git remote add origin https://github.com/nafeeur10/rental.git

Error:

fatal: remote origin already exists.

Then

git push -u origin master

Error:

git@github.com: Permission denied (publickey). and the repository exists.

What is the problem and what should I do actually?

Answer 1

1.If origin url is already added, you can use "git remote -v " to see what origin is already added.

Since you have origin already set to some url, you can update origin url using

git remote set-url origin https://github.com/nafeeur10/rental.git

2.You might not have permission to push to master branch. Try pushing to new develop branch.

Answer 2

fatal: remote origin already exists.

This error message indicates remote is already configured with the same name. Either add the new remote with a different name or update the existing one.

To set new remote:

$ git remote set-url origin https://github.com/nafeeur10/rental.git

Or can update existing one:

git remote add origin1 git@github.com:ppreyer/first_app.git 

Doing so, everywhere in "origin" you should replace it with "origin1". For example $ git push origin master should now be $ git push origin1 master.

Answer 3

Your remote origin exists. So you are probably getting this error because you didn't initialize or reinitialize(in case of a new commit in previously existing repository) your git repository. First type command "git init". After that try this command.

git push -u origin master

Then you might be prompted for authentication. Provide your credentials and changes will be pushed to your remote repository.
