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

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
