Ever faced with an error like this? is a very common error in Linux systems.

Here's how you can solve it.

Step 1: Log into the system as the root user.

Step 2: Two things need to be checked. Let's assume that the machine name is machine1.

The first thing to be checked here is if the entry in the hostname file of the machine is correct.

This can be checked with the following command:

sudo nano /etc/hostname

If the machine name machine1 is not there in this file, enter it here.

Step 3: Check the .

The file /etc/hosts is usually the commonplace missing the machine name in most of the cases. Open and check this file if the machine1 is entered hereafter the line.

sudo nano /etc/hosts

The final file should look something like this:

127.0.0.1    localhost.localdomain localhost  
127.0.1.1    machine1

The hostname will not change until you reboot. So if you have made any changes as said above, restart the system with this command.

sudo systemctl restart

This should remove the error finally.
