Did you delete the /etc/sudoers file? Did you change the permissions on /etc/sudoers?
Also sudo su is a dumb way to become root, unless you have some really ancient version of sudo.
man sudo
...
-i, --login Run the shell specified by the target user's password database
entry as a login shell. This means that login-specific
resource files such as .profile, .bash_profile or .login will
be read by the shell. If a command is specified, it is passed
to the shell for execution via the shell's -c option. If no
command is specified, an interactive shell is executed. sudo
attempts to change to that user's home directory before
running the shell. The command is run with an environment
similar to the one a user would receive at log in. Note that
most shells behave differently when a command is specified as
compared to an interactive session; consult the shell's manual
for details. The Command environment section in the
sudoers(5) manual documents how the -i option affects the
environment in which a command is run when the sudoers policy
is in use.

sudo -s can be useful as well (prevent ovewriting symbols from .bashrc).
sudo -s also allows accessing accounts without valid login environment like www-data etc.

I dont know exactly what my last colleague did but how to recover that as usual if it is physically accessible or volume can be mounted to another aws machine known that, I dont have physical access to machine as it is in the AWS cloud.
Do you have the actual root password so you can run su? Is there another account that you can log into that can run sudo? Is there an ssh key in the root account? Do you have access to AWS to boot the VM into single user or some other mode that can let you recover the VM?
ASKER
all accounts are configured to get to root by running sudo su as I dont write root password
You only answered my first question. What about the rest?
ASKER
No I dont have root password all other accounts have same error I can detach volume and attach it to another machine
