How to upgrade Ubuntu 20.04 LTS to Ubuntu 20.10 ‘Groovy Gorilla’

Ubuntu’s long-term support (LTS) releases are the best when reliability and predictability are your top concerns. Released earlier this year, Ubuntu 20.04 “Focal Fossa” is Ubuntu’s brand new LTS release which will receive official updates till 2025 (there is a paid support plan if you intend to use it even further).

But a lot of regular users prefer the latest software even though theoretically you might have a sacrifice a small amount of reliability and thereby your peace of mind. To be honest, I almost never had any major stability or reliability issues with non-LTS Ubuntu releases.


But the only hassle is the requirement for a full OS upgrade every 6 months or so. Given how easy it is to upgrade an Ubuntu OS (which you will witness below), even that is not a deal breaker. Ubuntu 20.10 ‘Groovy Gorilla’ is the latest non-LTS release from Canonical. And here’s how you upgrade from Ubuntu 20.04 LTS to Ubuntu 20.10 ‘Groovy Gorilla’.

Upgrade to Ubuntu 20.10 from Ubuntu 20.04 LTS

If you are on Ubuntu 20.04, you most probably won’t get notified about the availability of a new OS, until the next LTS release is due (which in our case will be Ubuntu 22.04 LTS in 2022). To change that, you need a small edit in the following file: etc/update-manager/release-upgrades

Fire up your Terminal and type the following command

sudo gedit /etc/update-manager/release-upgrades

ubuntu 20.10

Notice the last line in the document.

The value of ‘Prompt’ is set to ‘lts’. Change the value to normal, as in ‘Prompt=normal’

Now, do a full system update.

sudo apt update && sudo apt dist-upgrade

And finally, the the OS upgrade. Make sure you have everything backed up and ready. This is very important. 9 out of 10 times the upgrade will go hassle-free, but you’ve to be prepared for that odd chance of things going wrong. Also make sure you laptop is plugged in because this is going to take some time.

sudo do-release-upgrade

That is all. The system will take you through the required steps. And hopefully you’ll have the brand new Ubuntu 20.10 “Groovy Gorilla” up and running in a few hours. Happy Ubuntu-ing!
