Want to upgrade to Ubuntu 20.0? In this post we show you how to make the leap to the latest long term support without having to reinstall from scratch.

Complete Guide Ubuntu 20.04 LTS: Everything You Need to Know

The steps required to upgrade to Ubuntu 20.04 from Ubuntu 18.04 work right now, no need to wait for point releases.

Ubuntu 19.10 support ended on July 17. To keep getting updates and security patches you need to upgrade to 20.04 LTS.

But you don’t need to download an .iso, fuss around with flashing it to USB thumb drive, or risk losing any of your files — you can upgrade to Ubuntu 20.04 directly. All you need is a half-way decent internet connection and a bit of patience.

Before you go any further (whenever you choose to) be sure to backup any important files, system settings, dot files, or critical content. It also helps to keep some ‘rescue’ media to hand should things go wrong. You never know.

How to Upgrade to Ubuntu 20.04

Ubuntu 20.04 was released on April 23, 2020. It is supported by 5 years of app and security updates, taking you through to July 2025.

You can upgrade to 20.04 from Ubuntu 18.04 or Ubuntu 19.10.

If you run Ubuntu 16.04 LTS you will need to upgrade to 18.04 first.

To upgrade to Ubuntu 20.04 you will need:

  • A working internet connection
  • A fully-updated Ubuntu 18.04 LTS or Ubuntu 19.10
  • A pinch of patience

The exact steps required for each distro different slightly so do read carefully.

Note: you can NOT upgrade to Ubuntu 20.04 from a 32-bit Ubuntu release. Support for 32-bit architecture was dropped in 19.10.

Upgrade from Ubuntu 18.04 LTS

upgrade to ubuntu 18.10 from 18.04

The easiest way to upgrade to Ubuntu 20.04 is from an earlier version — but you can’t do it automatically until the first point release is made.

Why the wait? Well, it’s a standard practice aimed at maximising stability, which is what an LTS is all about after all.

Once Ubuntu 20.04.1 LTS is released all users on 18.04 will begin to receive an upgrade notification.

To upgrade to Ubuntu 20.04 from 18.04 before the point release goes live:

  • Open “Software & Updates”
  • Select the “Updates” tab
  • Change “Notify me of a new Ubuntu version” to “For any new version”

Now when the software updater does its routine check it’ll ‘see’ the new release and let you know about it. You just need to click the “Upgrade” to, well, you can guess the rest! 😉

Don’t see the prompt? You can ‘force’ upgrade Ubuntu 20.04 from Ubuntu 18.04 using the command:

sudo do-release-upgrade -c

Upgrade from Ubuntu 19.10

You can upgrade Ubuntu 19.10 to 20.04 from April 23 using the built in software updater tool.

The upgrade prompt will not appear to everyone at the same time, so if you don’t see it instantly on release day do don’t panic and try to be patient.

As long as your system is fully up-to-date you’ll be notified that the upgrade is available in a. desktop pop-up. Just click the ‘Upgrade…’ button when you see it to do the rest.

Impatient? You can force check for a new stable Ubuntu release using this command:

sudo do-release-upgrade -c

Follow the instructions as presented.

Upgrading before April 23

This section was written prior to the final release and is, as of April 23, no longer required.

If you upgraded to 20.04 before April 23 you do NOT need to reinstall anything to get the ‘final’ version. Just keep installing any (and all) pending software updates and you’re good to go.

To force upgrade to Ubuntu 20.04 run:

sudo do-release-upgrade -d

This command checks for a new development release, disables all third-party PPAs, and rewrites your system’s apt list to point to focal development branches (from where it fetches updated packages required to complete your upgrade).

do-release-upgrade command

Do not press any other button(s) after you issue the command. Wait for it to calculate the changes. Providing your internet connection is reliable, proceed as directed.

If you choose to decline the upgrade when prompted you WILL need re-enable the bionic (18.04) or eoan (19.10) repos manually. This is NOT done automatically.

The majority of the upgrade happens automatically, meaning you don’t need to do anything other than wait (and watch all the lines whizz past you in the terminal).

That said, don’t abandon your system entirely as, config dependent, you may be required to press Y or N to okay the odd package overwrite at some point during the process (and it won’t budge until you do).

Once done, just reboot your system when prompted to enjoy the refreshed Focal Fossa experience firsthand.
