If you've ever tried running a command in Debian 10 and received an error message saying "sudo command not found," you're not alone. This frustrating issue can be caused by a variety of factors, but fortunately, there are several ways to fix it.

First, it's important to understand what the sudo command is and why it's necessary. Essentially, sudo (which stands for "superuser do") allows you to run commands with administrative privileges. This is important because many commands require elevated access in order to function correctly or make changes to your system.

So, if you're getting an error message that says "sudo command not found" when you try to run a command, it means that your system isn't recognizing the sudo command. There are several potential reasons for this:

The sudo package may not be installed on your system
Your system may be configured to not recognize sudo
There may be a problem with your PATH environment variable

The good news is that each of these issues can be resolved with a few simple steps. Here are some potential fixes:

Install the sudo Package

If the sudo package isn't installed on your system, you'll need to install it first. To do this, you'll need administrative privileges, so you'll need to either log in as the root user or use the su command to become root:

su root

Once you're root, you can use the apt-get command to install sudo:

apt-get install sudo

This should install the sudo package and allow you to use the sudo command.

Configure Your System to Recognize sudo

If your system is configured to not recognize sudo, you'll need to edit your sudoers file to add your user account. To do this, you'll need to log in as the root user and edit the sudoers file:

su root  visudo

This will open the sudoers file in the vi text editor. Scroll down to the section that says "User privilege specification" and add the following line:

yourusername ALL=(ALL) ALL

Be sure to replace "yourusername" with your actual username. Save and exit the file (in vi, this is done by pressing Esc to exit insert mode, followed by :wq to save and quit).

Now, when you log in as your user account, you should be able to use the sudo command.

Check Your PATH Environment Variable

If there's a problem with your PATH environment variable, your system may not be able to find the sudo command. To check your PATH variable, you can use the following command:

echo $PATH

This will output a list of directories that your system searches when you run a command. You should see "/usr/bin" in the list, which is where the sudo command is located. If you don't see it, you'll need to add it to your PATH variable.

To do this, you can edit your ~/.bashrc file (which controls your shell environment) and add the following line:

export PATH=$PATH:/usr/bin

Save the file and exit, then open a new terminal window or run the following command to apply the changes:

source ~/.bashrc

Now, when you run the sudo command, your system should be able to find it.

Hopefully, one of these fixes has solved your "sudo command not found" issue. If not, there may be a more complicated underlying problem, and you may need to seek further assistance.
