Ubuntu Pro & Cloudron

It looks like livepatch is out of beta now.
It gets activated automatically when you attach your machine to your Ubuntu Pro account:

sudo pro attach insertyourtokenhere

It did not require the installation of ubuntu-advantage-tools.
However, on my Ubuntu 22.04.1 LTS (Cloudron) machine, is asked me to install an update of these tools.
On my Ubuntu 22.04.2 LTS (non-Cloudron) machine, it already seemed to have the latest version.
That brings me to a question @girish: Is it OK to upgrade to 22.04.2 on the Cloudron machine?

[girish]

@nichu42 yes, should be OK to update the tools.

Thanks, but actually my question was about Ubuntu itself. Is it OK to upgrade from 22.04.1 to 22.04.2?

[girish]

@nichu42 yes, that should be ok as well.

Note: keeping the installation up to date doesn't upgrade to the kernel (5.15 -> 5.19)

• To check if you already have the new kernel:
  sudo apt list linux-generic-hwe-22.04 --installed

• To install the metapackage for the new kernel:
  sudo apt install linux-generic-hwe-22.04 --install-recommends

• Otherwise: sudo apt install --install-recommends (add an -s to first simulate updates)

All went well, thanks again! I am now on Ubuntu 22.04.2 LTS / Kernel 5.19 with livepatches activated. No problems at all during or after the upgrade.

How do you know that if the live patch is enabled?

On the documentation, I only see that kernel 5.15 is supported and not 5.19.

[necrevistonnezr]

@random_eric I took my information from here: https://www.omgubuntu.co.uk/2023/02/ubuntu-22-04-2-download

@necrevistonnezr
How do you know that the live patching is enabled for that kernel?
I just don't know how to check.

Found it:

canonical-livepatch status

returns

last check: 23 seconds ago
kernel: 5.15.0-67.74-generic
server check-in: succeeded
patch state: ✓ no livepatches needed for this kernel yet
tier: updates (Free usage; This machine beta tests new patches.)

last check: 1 minute ago
kernel: 5.19.0-35.36~22.04.1-generic
server check-in: succeeded
patch state: ✗ kernel version not supported
tier: updates (Free usage; This machine beta tests new patches.)

So based on the pattern in the docs,
the 22.04 hwe kernel will only be supported for live patching once the 24.04 LTS is released.

I was checking the livepatch status and received the info that I need to update the ubuntu-advantage-tools. I did that, and during the installation it told me that I need Kernel 6.2.0-26-generic, which has been now automatically been scheduled for installation. Feeling brave, I did a reboot. Now I am indeed running 6.2.0-26-generic:

last check: 38 minutes ago
kernel: 6.2.0-26.26~22.04.1-generic
server check-in: succeeded
kernel state: ✓ kernel is supported by Canonical until 2024-08-13
patch state: ✓ no livepatches needed for this kernel yet

No issues so far with Cloudron or any apps (although, to be honest, I don't even know if there are any problems to expect when doing a kernel update).

Anyway, while I'm on it. Is it advisable to go to the recently released Ubuntu version 22.04.3 LTS?

[nebulon]

At the moment with 7.5 only Ubuntu 20.04 and 22.04 are supported.

Ubuntu 24 is released? Where did you get this from?

[nichu42]

Sorry, I'm talking about 22.04.3

@nichu42 that you can safely upgrade to
