Sudo also called “superuser do” is a command in Linux that allows you to run high-privilege admin commands as a root user. It asked to enter your personal password and confirms your requests by checking a sudoers file.
After a fresh Debian 10 installation, you could not execute the privileges tasks by running the sudo command. You will get the error ‘sudo command not found in Debian 10′. The reason for this error is the sudo command isn’t included in Debian 10 by default.
