sudo: sorry, you must have a tty to run sudo
File not exist

In /etc/sudoers (or via visudo ) change

Defaults: requiretty

to

Defaults: !requiretty

The sudoers file does allow you a bit more granularity that to disable the feature for everyone. Instead you can just do it per user need and even for just the command necessary.
e.i.

Defaults:username !requiretty
