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
grep sudo /etc/group
command?sudo:x:27:manka,root
