How to Upgrade Ubuntu 16.04 to Ubuntu 18.04


For Linux Desktop users, this is the trending stuff all going into the Linux World.
Of Course there are a hundreds of Linux distros, but Ubuntu is one of the popular one as per distrowatch.

Ubuntu provids two types of releases

  • Standard release. 
  • Long Term Support (LTS) release. 


So what's the difference between these two ?
All it's support provided by Ubuntu aka Canonical
Standard releases for approx 1 year while Long Term Support is useful for approx 5 years.

Ubuntu 18.04 is an LTS release will be supported till 2023. 

If you are also a Ubuntu Desktop Fan and running Ubuntu 16.04, why wait let's upgrade.

But if you are running ubuntu 16.04 within your server, i recommend you to wait for a minimum of two months from release date.

Backup your data first.

We strongly recommended to backup all your important data from your Desktop to a remote location or into some external storage.

Update all your system packages.

sudo apt-get update
sudo apt-get upgrade

Install Update Manager 

sudo apt-get get install update-manager-core
Once the update-core-manager package has been installed, let's ensure it's config file is set to LTS
Open the file /etc/update-manager/release-upgrades file and make sure Prompt value is set to lts like below.
Prompt=lts

Upgrade your  Ubuntu from 16.04 to 18.04

Once you are done with the updation of file /etc/update-manager/release-upgrades updation , you are all set to upgrade your UBuntu to newer version of LTS that is 18.04.
sudo do-release-upgrade -d 
Once you have executed the upgrade command, you must stick to your computer for some more few minutes.
It will ask for few inputs from your side,  follow the prompts and choose the default ones, the entire upgrade time duration is totally dependent on your internet connectivity speed.

Once completed,  reboot your System and verify your Ubuntu Version.

lsb_release -a
You must see something like below


Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04
Codename: bionic
