when I write my password on terminal for sudo command, it gives me writing feedback even if I didn't modify the sudoers file. How can I fix this? This is my situation:
This is actually a change that was recently included in a round of updates to Loki. It is briefly mentioned in their new blog post. A package called
elementary-default-settings was updated to include a file located at
/etc/sudoers.d/pwfeedback, which changes this behavior when entering a password in the terminal.
If you wish to disable the feedback, try this command:
sudo mv /etc/sudoers.d/pwfeedback /etc/sudoers.d/pwfeedback.disabled
This will keep the file around in case you want to re-enable it, which you can do with the following:
sudo mv /etc/sudoers.d/pwfeedback.disabled /etc/sudoers.d/pwfeedback
