By mistake I entered the command 

sudo chmod -R 777 somefolder ./

Now I am unable to log in to my system as root user. I have the login loop problem

    Why would you want to log in as root? What directory were you in when you ran the command? If you have the error in your title, I guess you must have run it at least on `/usr` if not on `/`. Fixing *recursive* `chmod` is a pain... If you want the least hassle, get your data off there with a live USB and reinstall – Zanna Aug 11 '17 at 07:18

Hi i had a similar problem and this is how i solved it.

  • First reboot your machine and enter the recovery mode from your grub menu
  • Choose the drop to root shell option.This will prompt you with a control-D to continue just press enter

  • You are now in a root shell.Do the following

    mount -o remount,rw /
    chown root:root /usr/bin/sudo
    chmod 4755 /usr/bin/sudo
    exit

  • Go back to the menu and choose resume normal boot
