Enable password feedback when entering sudo password

From Pengwings

You need to add pwfeedback to the sudo defaults, there are two ways to do it, the latter is probably better

By editing /etc/sudoers

Run visudo (allows editing sudo config safely)

sido visudo

Find 'Defaults' section:

Defaults env_reset

Add pwfeedback to 'Defaults'

Defaults env_reset,pwfeedback

By adding a special sudoers.d custom rule file

Alternatively you can also add the following file

/etc/sudoers.d/enable-pwfeedback

Containing this string:

Defaults pwfeedback
