Install the update-manager-core package if it is not already installed:
sudo apt-get install update-manager-core
Edit the file /etc/update-manager/release-upgrades,
sudo nano /etc/update-manager/release-upgrades
and set Prompt=normal or Prompt=lts as shown below.
# Default behavior for the release upgrader. [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the release that immediately succeeds the currently-running # release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that this option should not be # used if the currently-running release is not itself an LTS # release, since in that case the upgrader won't be able to # determine if a newer release is available. Prompt=normal
Now, it is time to upgrade your server system to latest version using the following command:
sudo do-release-upgrade -d
Follow the on-screen instructions. You’re done!!.
