Issue in running sudo visudo command?

Question

I get the following error when running sudo visudo on my Ubuntu:

visudo: /etc/sudoers busy ,try again later

Answer 1

Had you already run visudo ? That error indicates that the file is already being edited. First stop the other process with:

killall visudo

Also run

visudo -c 

to make sure that the sudoers file was not corrupted.

Answer 2

If the accepted answer not working for you, then you can try this:

List all processes that use sudo

ps -ef|grep sudo

then you should kill all process id that existed in the second columns, by using this command:

kill -9 YOUR_PROCESS_ID
