Solution to the emergence of-bash: sudo: command not found in Debian system

I believe that many students have encountered problems like-bash: sudo: command not found when executing commands after installing a new server. The following is a tutorial. The following actions can be solved. First of all, let's make sure and execute the following command to see if the file exists:

find /etc/sudoers.d

If you return No such file or directory, it means that your system does not have sudo installed.

Here are the installation commands:

apt-get install sudo

If you are prompted for an error that Unable to locate package sudo, execute the following command first:

apt-get update

Then execute sudo apt-get install.
