GitHub: Permission denied (publickey). fatal: Could not read from remote repository

• On your GitHub profile there is an Edit Profile button.
  It is located on top-right corner of the webpage.
• Press it and you will see left Personal Settings menu.
• Inside that menu find SSH and GPG keys option and press it.
• You will see an option New SSH key to add new key.

1. Generate SSH key using ssh-keygen -t rsa -b 4096 -C "your email".
2. Copy the output of cat ~/.ssh/id_rsa.pub to your clipboard
3. Paste the above copied output to the form at https://github.com/settings/ssh/new

1. generate your key

   ssh-keygen

2. Visualize your keys

   ls ~/.ssh

   id_rsa id_rsa.pub

3. Start the agent

   eval ssh-agent

4. Add your key to the agent

   ssh-add ~/.ssh/id_rsa

I was having the same problem with my ssh connection. I tried to work it through ssh, but couldn’t find a working solution for it. So, in that case, I changed my remote URL from SSH to HTTPS. I used the command: $ git remote set-url origin https://github.com/USERNAME/REPOSITORY.git. You can see your remote url changed using: $ git remote -v.

You can find more detail on Here

This will change your remote URL to HTTPS so you will now have to type your GitHub username and password to push your project to the remote repo. I know ssh is easier than HTTPS meaning that you don’t have to type out your username and password, but this might be helpful if you didn’t find any solution for fixing it through ssh, and you are in a rush to push your code to your repo.

For me I had to set what host to use what SSH key. In your local machine SSH folder, usually under ~/.ssh create/edit the file called config using your preferred editor like vim or gedit

vim ~/.ssh/config

and add the following with your git Host, HostName, and ssh IdentityFile (your ssh private key file path):

Host gitlab.example.com
    HostName gitlab.example.com
    IdentityFile /home/YOURUSERNAME/.ssh/id_rsa

1. make sure you have named the “public key” and “private key” files properly; precisely like “id_rsa” and “id_rsa.pub”. This is something that you can find in your users/.ssh folder.

2. add the public key in GitHub

3. Restart your terminal ( bash supported) and try to clone again

if you have the write access to the repo, you should be good to go after these changes.

Talking from experience (after spending an hour), I could not find any info on any forum that stated that we have to explicitly keep the name of the private and public file as mentioned above.

Happy coding!

If any of you facing same kind of issue on Bitbucket then here is the solution:

Issue:

Please make sure you have the correct access rights and the repository exists.

Solution:

Goto: https://bitbucket.internal.abc.com/plugins/servlet/ssh/projects/REM/repos/jenkinspipeline/keys 1) Add keys Copy/paste the id_rsa.pub key value there:

Done! Now you can able to clone the git repository

I got it after wasting a lot of time…

In the accepted answer of Shravan40 everything was ok, but me idiot added at github.com a new repository with adding a new README.md and this caused the error

 ERROR: Repository not found.
 fatal: Could not read from remote repository.
 Please make sure you have the correct access rights

after a lot of tries, i added a new repository without a new README.md and everything was ok, but i don´t know the reason. 🙁 Till yesterday, when on a new try i finally noticed it…

So my solution in addition to Shravan40s answer is

maybe it will help someone…

In my short experience using git with linux, I found there were two simple answers to this error.

run these commands in this order

git remote set-url --add origin <https://github.com/username/repo>
git remote set-url --delete origin <[email protected]:username/repo>

This will reconfigure your config file to use HTTPS origin instead of SSH.

now try running push or pull commands.

OR

Reboot your linux VM (if you’re using one) and/or host machine. Rebooting has resolved the issue for me more than once.
