\302\226git@github.com: Permission denied (publickey). fatal: Could not read from remote repository.

This error message indicates that there is an issue with your SSH key authentication when trying to access a GitHub repository. Here are some steps you can take to resolve this issue:

Check that you have added the correct SSH key to your GitHub account by going to your account settings and navigating to the "SSH and GPG keys" section. If you haven't added a key or added the wrong key, follow the instructions provided by GitHub to add the correct key.

Ensure that your SSH key is correctly configured on your local machine. You can do this by running the following command in your terminal:
ssh -T git@github.com
This should return a message confirming that you have successfully authenticated with GitHub.

If the above steps don't work, you may need to generate a new SSH key and add it to your GitHub account. You can follow the instructions provided by GitHub to generate a new key and add it to your account.

If you're still having issues, try using HTTPS instead of SSH to clone the repository. You can do this by using the HTTPS URL for the repository instead of the SSH URL.
For example:
git clone https://github.com/username/repo.git
This will prompt you to enter your GitHub username and password for authentication.
