I am able to login to my account but can't do anything related to superuser now. Updates, sharing, sudo and all things say authentication failed.

I tried to correct that by going in recovery mode and adding my user to sudo but when i use adduser command, i get error message that group sudo does not exist

I searched for the error but could not get any link answering this :(

Thanks in advance

Had the same problem. Fixed it by addgroup sudo as root, and then changing the Group ID to 201 in /etc/groups. (Pick an unused number < 1000)
