How to upgrade to Linux Mint 19.1

In order to restore the previous behavior you can remove a file:

/etc/sudoers.d/0pwfeedback

The removing of the file is simple with command rm:

sudo rm /etc/sudoers.d/0pwfeedback

I recommend you to make a copy of this file if you want to restore the behavior for showing password. And this is the recommended way when you are deleting files from your system. Back up can be done by:

sudo cp /etc/sudoers.d/0pwfeedback ~/Downloads/

And then you can delete the file. Later if you want to restore it you can run:

sudo cp ~/Downloads/0pwfeedback /etc/sudoers.d/

Restore the '*' behavior

The file content is simple one so you can simply recreate the file with this content:

Defaults pwfeedback

Example command would be:

sudo touch /etc/sudoers.d/0pwfeedback
echo "Defaults pwfeedback" | sudo tee /etc/sudoers.d/0pwfeedback

Note:

If you try to use:

echo "Defaults pwfeedback" >> /etc/sudoers.d/0pwfeedback

you will get an error like:

echo "Defaults pwfeedback" >> /etc/sudoers.d/0pwfeedback
bash: /etc/sudoers.d/0pwfeedback: Permission denied

Note: If you try to rename the old file with:

sudo mv /etc/sudoers.d/0pwfeedback /etc/sudoers.d/0pwfeedback_bak

This will not work or at least in my tests it didn't make any difference.
