This is a question that gets asked every now and then, so I thought it was time to have something in writing to clear this up.

As of this post, there is no software from us to upgrade you from one Series of LL to the next.

So can it be done?

It's linux and free software, so most things are possible. Theoretically, you could just change the sources in your /etc/apt/sources.list file from eg. focal (20.04) to hirsute (21.04), run Install Updates and wammo, you're running the latest Ubuntu base.

So from:

Code: [Select]
# deb http://us.archive.ubuntu.com/ubuntu/ focal main restricted

# deb http://us.archive.ubuntu.com/ubuntu/ focal-updates main restricted
# deb http://security.ubuntu.com/ubuntu focal-security main restricted

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://nz.archive.ubuntu.com/ubuntu/ focal main restricted
# deb-src http://us.archive.ubuntu.com/ubuntu/ focal main restricted

## Major bug fix updates produced after the final release of the
## distribution.

Will this method go smoothly?

Don't just assume that it will. You may have PPA's that don't have a hirsute repo yet, LL's custom software is ONLY written for the current release (makes sense right). There are 1000's of computers out there with just as many unique configurations. It is unrealistic and unfair to expect LL to support every unique configuration in existence in order to guarantee a perfect Series to Series upgrade.

In a test of a fresh LL 5.4 install, I ran updates, rebooted, then changed my sources from focal to hirsute and it went smoothly. Or so it seemed.

Installing hirsute (Ubuntu 21.04 - Hirsute Hippo) via Install Updates on a freshly installed and updated 5.4:



Success?!?



After reboot:









Can I choose any future version of an Ubuntu base, or do I have to stick with LTS?

You can choose any future version. DO NOT attempt an earlier version. Bad, bad news.

What's the best way to test this?

Duplicate your set up exactly as it is in a VM, then test the upgrade process. Just keep in mind this will not necessarily and accurately reflect in the same hardware outcomes as a VM is mostly simulated hardware, and not passthrough (although eg nVidia now allows passthrough).

We're not going to support this because of the ungodly amount of extra support it will create, and this community is nicely balanced at the moment. We can't stop you from trying, it is after all free software, we're just not going to support every single error as a result of this unpredictable procedure.

So when someone asks now, "Can I upgrade my Linux Lite from one Series to the next?" Simply reply, "Yes, but it is not supported, and here is a thread explaining why."

This is best attempted on a fresh install after the first run of Install Updates. Any later, and that's where the complications will arise.

Will we one day support it?  That depends on how our base (Ubuntu) evolves. Never say never, right?

  • Linux Lite: 5.4 64bit

  • MEMORY: 8Gb

  • VIDEO CARD: NVIDIA GTX1070

  • Kernel: 5.x
Thanks for the write-up.

I am still on 4.2 and tbh am too nervous to update since I made a lot of changes to the system for my comfort that I think will break if I update.
