You are having the exact same issue, sudo is complaining about being
executed without a tty.
Could you please take a look at the various links I provided to you and
check ?
Basically, you can quickly disable requiretty on sudoers and retry, to
check if that fixes the problem.
Which is your distro ?
Could you please paste /etc/sudoers ?
Also, please use 'sudo service quantum-XXX-agent restart' instead of
'sudo /etc/init.d/quantum-X-agent restart' directly.
