jenkins fails while restarting my sql "sudo: no tty present and no askpass program specified Sorry, try again."

Question

I just configured jenkins and in the pre-build steps i am trying to restart jenkins but i end up with the following error

Commencing build of Revision c5b9f8daac092efc5396d80f568a2cf89ae8b697 (origin/HEAD, origin/master)

I googled and saw some answers at Jenkins out of nowhere starts failing with sudo: no tty present and no askpass program specified

But unfortunately that didn't help me

My /etc/sudoers looks like this

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.

Answer 1

The "no tty present" error indicates that you have the 'requiretty' setting in your sudoers file. In your case, it is probably in /etc/sudoers.d. Once this line is there, it does not matter what group you are in - sudo will require a tty whenever it is executed.

To get around this, you need to either remove (or comment out) the requiretty line in the configuration file, or add a line to exclude your user from the requiretty setting. You can see how to do that here: Disable requiretty per user

Answer 2

By adding the following: Defaults:username !authenticate to your /etc/sudoers you should not get the error but this username will be accessible without asking for a password
