Privileges

Usually an error that is worded “Operation is not permitted (1)” is indicative of a user privilege or permission issue. Firstly make sure that the user used for ssh has the correct permissions. To set the user use sudo chown -R <user_name>.

Then you see if you have read and write permissions. To see current permissions run ls -ld <path>. To change the permissions run

    sudo chmod u+rwx <path>
