Password asterisk feedback mysteriously enabled
2
I have Ubuntu 16.04 installed on my machine and a while back something strange happened. All of a sudden I started getting password visual feedback (*) when entering the password for commands run with sudo.
I've checked the /etc/sudoers file and there is no pwfeedback entry for the defaults.
How can I determine why visual feedback is enabled and from where?

Check into /etc/sudoers and /etc/sudoers.tmp and /etc/sudoers.d.
Make sure the line
Defaults pwfeedback
is deleted.
If it is along like this
Defaults env_reset,pwfeedback
change it into
Defaults env_reset

That's because
visudo copies sudoers to sudoers.tmp for editing. When you finish editing, visudo copies it back. sudo doesn't read sudoers.tmp by itself. Create a sudoers.tmp outside of visudo that differs from your sudoersand see for yourself.– muru
