I am trying to add some file in a remote server by BigTuna (continuous integration tool), and it give me a error message. Any one have any idea how can I add that file to server?

sudo: no tty present and no askpass program specified

Answer 1

This is due to 'requiretty' option on /etc/sudoers. If you have access to it, you might just remove that option.

If not, there are other ways as well. Probably you are doing something like ssh user@host sudo do_something. You can try to add -t option to allocate tty by ssh (so it would be ssh -t user@host sudo do_something).

Answer 2

Your application use the sudo command in a no tty, you may bypass this by editing the file /etc/sudoers and comment this line :

Defaults    requiretty
