To fix this,

1. you’ll need to reset the permissions back to default:

   sudo chmod 600 ~/.ssh/id_rsa
   sudo chmod 600 ~/.ssh/id_rsa.pub
   

   If you are getting another error:

   • Are you sure you want to continue connecting (yes/no)? yes
   • Failed to add the host to the list of known hosts (/home/geek/.ssh/known_hosts).

2. This means that the permissions on that file are also set incorrectly, and can be adjusted with this:

   sudo chmod 644 ~/.ssh/known_hosts
   

3. Finally, you may need to adjust the directory permissions as well:

   sudo chmod 755 ~/.ssh
   

This should get you back up and running.
