In case you've missed the news, Ubuntu MATE 20.04 Focal Fossa has been released!
Take a look at what's new:
Upgrading from 18.04 LTS
This release is still officially supported for another year (April 2021).
You'll see this notification to upgrade in a couple of months when the first point release is available (20.04.1). This is like a stability safety net, to allow for early 20.04 issues to be ironed out.
Upgrading from 19.10
Being a short-term release, you must upgrade within 2 months (June 2020).
Notifications in Software Updater should start to appear soon.
Upgrade before the prompt
If your system hasn't been invited to upgrade, press Alt + F2 and type:
update-manager -c -d
Disregard the "development release" message, as you can be assured that 20.04 has been released and this won't jump onto a newly opened 20.10 branch (unless you try to do this from 20.04, of course!)
Alternately, upgrades can be performed via the Terminal:
sudo do-release-upgrade -d
As always, it is a good practice to backup your computer.
Right here - currently just for 64-bit PCs and Macs:
We've also recently updated the website to provide more details on how you can get involved and get a feel of what makes up the MATE desktop experience.
What about 20.04 for the Raspberry Pi and GPD?
There are no fixed timelines at the moment, however our project leader has been live streaming progress updates during the past few months and has recently polled which you'd be interested to see next:
(1) "Desktopify Ubuntu on Raspberry Pi" - a live stream series to create a script that you can run on a Raspberry Pi running Ubuntu server and it will augment it to run a desktop flavour of your choice, including appropriate tweaks to optimise for desktop.
(2) "Ubuntu MATE 20.04 images for GPD devices" - a live stream series to update the tooling and then build/test/publish new images for the family of GPD devices.
