Resolving the Permission Denied (Publickey) error in Git
This article describes the steps to resolve the Permission Denied (Publickey) error in Git. If you are a regular Git user, you may encounter such an error while cloning a remote repository.
In this case it just means the server rejected your request. How did you fix it?
Setting up a public/private key pair in Git
Open your terminal and run the following command to access your .ssh directory.
$ cd ~/.ssh && ssh-keygen
Copy one of the following commands according to your system and execute it.
On Linux:
cat id_rsa.pub | xclip
On OS X:
cat id_rsa.pub | pbcopy
On Windows:
cat id_rsa.pub | pbcopycat id_rsa.pub | clip
and
cat id_rsa.pub | clip
Adding a key to an account
Now you can add the key to your account. You can do this by making a few adjustments to the .config file as shown below.
$ git config --global user.name <Your-Name>
$ git config --global user.email <Your-Email>
If you have already generated a public/private key, the next steps are as follows.
Check the private key
The following command determines which private key corresponds to your local computer.
eval $(ssh-agent -s)
Run the following command to define the location of the key.
ssh-add ~/.ssh/id_rsa
As mentioned earlier, you can now configure SSH keys by editing the .config file.
In short, SSH keys are like passwords, but more secure because they are extremely difficult to decrypt. If you encounter Permission denied (publickey) in Git , you need to configure the key in the .config file as described above.
