EDIT: In case of error on screenshot, this is the message:
Failed to obtain administrator privileges: sudo: sorry, you must have a tty to run sudo
To enable use of 'sudo' by applications without a terminal window, please disable 'requiretty' option in '/etc/sudoers'. Newer versions of sudo automatically determine whether a terminal is required ('requiretty' option is obsolete).
