I have removed a user from the sudoers file but he still have root acces

Question

i want to prevent all the users from becoming a root user

i have a user called sohaib i removed him from the sudo group using

gpasswd -d sohaib sudo

and also i've edited the /etc/sudoers file , i have commented the

# Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL

but the user still can use the

sudo -i

and become a root , i don't wanna any user to become a root including the first created user too (sohab)

perhaps there's a file in the /etc/sudoers.d folder granting the user sudo access — Jaromanda X

you are right , I've find a 90-cloud-init-users file that has some rules , it grants that user access without a password — SohaibMan

The solution was to also change all the relevant files in the /etc/sudoers.d directory, specifically a file called 90-cloud-init-users.
