    Did you do what it says to do at this link: https://docs.npmjs.com/getting-started/fixing-npm-permissions That is the most brain-dead method of forcing an install to work I have ever seen. `chown -R myuser /usr/local`? Even for `/usr/local`, that is epically stupid. And you've apparently found out why. – Andrew Henle May 03 '16 at 12:14

First restart your pc, and press the ESC key while Ubuntu is booting.

This will bring you up the boot menu.

Select Advanced Options.

Select your OS version in (recovery mode), and press Enter Key.

It will bring you up another screen. Now select “Drop to root shell prompt” and press Enter.

It will load a command line at the bottom of the screen.

Now run each of the following commands.

mount -o remount,rw /
mount --all
chown root:root /usr/bin/sudo
chmod 4755 /usr/bin/sudo
shutdown -r now

Its beacuase of Permission issue

 $ su
 Password: <type your root password>

Switch to root user and run the command

# pkexec chmod a=rx,u+ws /usr/bin/sudo

Then check it by typing from the user

$sudo -l

it Works fine for me

Cheers....

To solve this issue, you need to boot into recovery mode which provides a scroll-down menu with an option to drop down to a root shell.

And type these commands one after another:

# remount disks in read-write mode
mount -o remount,rw /
mount --all

# return ownership
chown root:root /usr/bin/sudo

# fix permissions
chmod 4755 /usr/bin/sudo

After that, you can reboot and log in again.

You may try this, to know if It worked:

sudo -l
