If changing the hostname in a Debian system does not take effect after a reboot, you can try the following solution:<\/p>\n

    \n
  1. Edit the\/etc\/hostname file: Make sure to update the new hostname in the \/etc\/hostname file after changing the hostname. You can open the file and edit the hostname using the command sudo nano \/etc\/hostname, then save and exit.<\/li>\n
  2. Edit the \/etc\/hosts file: Similarly, make sure to update the new hostname in the \/etc\/hosts file. You can use the command sudo nano \/etc\/hosts to open the file, edit the hostname, save, and exit.<\/li>\n
  3. Restart network service: Use the following command to restart the network service in order for the new hostname to take effect.<\/li>\n<\/ol>\n
    sudo systemctl restart networking\r\n<\/code><\/pre>\n
      \n
    1. Restarting the system: The last solution is to try restarting the system in order to make the new hostname take effect.<\/li>\n<\/ol>\n
      sudo reboot\r\n<\/code><\/pre>\n
      After following the above steps, you should be able to resolve the issue of Debian system not rebooting after changing the hostname. If the problem persists, further investigation and trying other solutions may be necessary.<\/p>\n","protected":false},"excerpt":{"rendered":"
