I don't know what's wrong in my pc. It runs on Ubuntu 16.04.
When I give sudo command, it asks for password. When I give password, it does not accept.
sudo -i
[sudo] password for alpha:
Sorry, try again.
[sudo] password for alpha:
Sorry, try again.
[sudo] password for alpha:
sudo: 3 incorrect password attempts
alpha@alpha-Inspiron-15-3567:~$
The password is correct, I checked that. The keyboard layout is okay, I typed the exact password.
To fix this I tried to follow this: Cannot run any sudo command
The Simple fix one did not work, so I tried the complex fix one, rebooting in recovery mode.
Got to this step:
bit I could not enter the whole command of
mount -o remount,rw /
chmod chmod u=rwxs,g=rx,o=rx /usr/bin/sudo /usr/bin/pkexec
exit
before I could complete /usr/bin/sudo, it started to run commands on its own and resumed.
So, here I am, not understanding anything. Can anybody help me ?

chmod
is repeated twice:The correct command is:
