Ubuntu 20.04.6 LTS is now available to download.
A point-six release?! They’re a bit unusual. Long-term support releases typically only receive five point releases during their support cycle so what’s going on?
I’ll quote Ubuntu’s Graham Inggs. They explained why this exceptional release was required in a mailing list post sent earlier today (March 23):
“Unlike previous point releases, 20.04.6 is a refresh of the amd64 installer media after recent key revocations, re-enabling their usage on Secure Boot enabled systems.”
You can read more about the issue on Launchpad (not that you need to – it’s now fixed, after all).
Additionally, Ubuntu 20.04.6 LTS takes the opportunity to bundle up a load of high-impact security fixes and bug banishments. A full list of changes between Ubuntu 20.04.5 and 20.04.6 is available on the Ubuntu Wiki.
Now, I don’t imagine many of you out there plan to download and install an older LTS release. Ubuntu 22.04 LTS is more current, has newer packages, better hardware support, and so on.
But on the off-chance are you are do make sure you’re grabbing the latest version of the installer. This will ensure everything is tickety-boo when it comes to installation. You can get it from the Ubuntu website directly when selecting the “20.04” release to download, or just jump straight for the release server.
Already using Ubuntu 20.04 LTS? You don’t need to do anything. As long as all software updates have been installed you’re riding the exact same release. The core reason for this point release was to fix new installs.
