Do the following:

  • Step 1. sudo nano /etc/hosts

  • Step 2. change your-current-hostname to your-new-hostname. Then save the file.

  • Step 3. sudo nano /etc/hostsname

  • Step 4. change currently entered hostname in that file and enter your new hostname. Save the file after.

@thefliik - Sorry for that typo.
/etc/hostsname ...should be /etc/hostname.
