Ubuntu Pro & Cloudron

[robi]

"Starting with the Ubuntu 16.04 edition and including the later LTS versions, Canonical will offer expanded security coverage for critical, high, and medium Common Vulnerabilities and Exposures (CVEs) to all of Ubuntu's open-source applications and toolchains for ten years," reports ZDNet.

Free for personal use on up to 5 servers:
https://ubuntu.com/blog/ubuntu-pro-beta-release

• One of the benefits is kernel live patch

@staff any issue if users enable this on Cloudrons?

UPDATE: Does not appear to be.

@robi A couple of days ago, I activated Ubuntu Pro on two machines (physical server and VDS). So far, so good. But I have not yet been able to check whether Cloudron can update the system with LivePatch enabled.

@WiseMetalhead Thanks for chiming in.

I tried to enable it on an 18.04 machine, however it failed as the 'pro' command doesn't exist

You need to install ubuntu-advantage-tools first, then check Ubuntu Pro with command:

pro --version

@WiseMetalhead Thanks, I have installed the package and by default it enables esm & livepatch.

From the guide it seems the rest is automated via apt, so as Cloudron runs apt upgrade for security updates it should pull in the above too.

Given that Ubuntu Pro has it's own terms/license, don't think it's right for us to auto-enable this without end user permission. Also, "personal use" is hard to determine for us.

But I can maybe add this to https://docs.cloudron.io/installation/

Looks like in this case it just means "5 or fewer machines" (unless you are an official Ubuntu Community member, and then it's 50 machines)

"Free for personal use. Anyone can use Ubuntu Pro for free on up to 5 machines" -- https://ubuntu.com/pro

I can't seem to find any info on that, got a link?

I couldn't find any when I looked earlier either, but imagine it's somewhere since you pay for it. (even a web search cannot find it!)

@jdaviescoates @girish It's in beta, so likely won't have those finalized until it's GA.

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.

@girish said in Ubuntu Pro & Cloudron:

@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)

[nichu42]

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.

@necrevistonnezr
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

[random_eric]

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

-- edit --

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.

[nichu42]

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.
