[Ssh] No tty present and no askpass program specified

[roma-glushko]

I've tried to configure postfix on my removed host via SSH:

public function configEmailForwarding()
{
$this->taskSshExec('s', 'dev')
->port(self::PORT)
->exec('cat /etc/postfix/virtual_forwardings.pcre')
->exec('cd /var/spool/postfix/pid')
->exec('sudo rm master.pid')
->exec('sudo service postfix restart')
->run();
}

Then I've executed this action:
robo.phar config:email-forwarding
and I've got the following issue:

sudo: no tty present and no askpass program specified

So It couldn't show me request for password.
Any ideas why?
