Pycharm Error "fatal: Could not read from remote repository."

I just encountered very unpleasant error with Pycharm when trying to push or pull to my private repository:

Git Pull Failed: fatal: Could not read from remote repository.

The problem and solution is as follows. I use SSH key for login into GitHub and Pycharm needs to know about it. Unfortunately, Pycharm supposes that your key to GitHub is exactly in ~/.ssh/id_rsa and ~/.ssh/id_rsa.pub. So solution is to create symlinks:

cd ~/.ssh
ln -s github_key_name id_rsa
ln -s github_key_name.pub id_rsa.pub

Everything should work now.
