sudo: no tty present and no askpass program specified

Question

SU access to our Bamboo Agents has suddenly stopped working. The first time any script in a Bamboo Job tries to invoke `sudo` we get:

(In at least several examples, `yum` is the command we're trying to run.)

All of these scripts were running happily 12 hours ago. We have only just started looking into what may have happened. Any pointers?

Thanks.

The underlying problem was that `yum` didn't exist on the system because it was an Ubuntu image intended for a different plan. (Ubuntu uses `apt-get`, not `yum`.) A change had been made to that Ubuntu image which accidentally caused it to become eligible for use on a plan for which it was not suitable.

on most *nix systems you can type visudo as root and look for something called Disable requiretty. Comment this out save and exit.
