ERROR os "ubuntu" version "24.04" not found #107

Bug Description

I couldn't deploy Canonical K8s charm on an series other than 24.04 - even when explicitly specifying the Ubuntu series.

If I run: juju deploy k8s my-k8s-test-application --channel=latest/edge --revision=59 --series=jammy Juju says: WARNING series flag is deprecated, use --base instead ERROR os "ubuntu" version "24.04" not found

If I run: juju deploy k8s my-k8s-test-application --channel=latest/edge --revision=59 --base='ubuntu@24.04' Juju says: ERROR os "ubuntu" version "24.04" not found

The current workaround is: using revision 47 - later revisions fail.

To Reproduce

  1. juju deploy k8s my-k8s-test-application --channel=latest/edge --revision=59 --base='ubuntu@22.04'
  2. Fails.

Environment

stg-is-new-canonical-k8s-testing@is-bastion-ps6

Channel: latest/edge Failing revisions: 48 and above Working revisions: 47 and below Juju Controller/Model: 3.1.8 Juju client: 3.1.8-ubuntu-amd64

Relevant log output

`juju debug-log` is empty because nothing is even deployed.

Additional context

We have Ubuntu 24.04 available on the cloud. For instance, juju add-machine --base="ubuntu@24.04" works and creates a Noble VM.

i'm not sure how to deploy to noble. I think this is a issue of juju

The charm is ready to support 24.04 when juju can make it work. I've been trying with juju3.5

Strangely running juju deploy k8s focal-k8s --channel=1.30/edge --base=ubuntu@20.04 on my environment (juju v3.1.8) shows this error: ERROR storing charm "k8s": retrieving essential metadata for charm "ch:amd64/focal/k8s-58": resolving origin for "ch:amd64/focal/k8s-58": os "ubuntu" version "24.04" not found (not found)

Even though I am explicitly asking for focal (20.04), it tries to deploy to 24.04 it looks like?

addyess commented 6 months ago

@hmlanigan Can you comment on whether or not juju is acting appropriately here

the k8s charm is

  - build-on:
    - name: ubuntu
      channel: "20.04"
      architectures: [amd64]

@addyess ubuntu 24.04 is supported with juju 3.4 and higher.

Hi everyone, could we please reopen this? ( cc @addyess @hmlanigan )

I don't want Noble; I want Jammy. The problem is:

$ juju deploy k8s my-k8s-test-application --channel=latest/edge --revision=59 --base='ubuntu@22.04'
ERROR os "ubuntu" version "24.04" not found

$ juju deploy k8s my-k8s-test-application --channel=latest/edge --revision=59 --series=jammy
ERROR os "ubuntu" version "24.04" not found

I asked for 22.04/jammy (using both "base" and deprecated "series"), it is still trying to deploy 24.04.

addyess commented 5 months ago

@mcarvalhor I don't get it. For me on juju 3.5 -- no worries with either of these

Does it work on 3.1.8 (the current prodstack version)?

yeah, confirmed it doesn't work right in juju 3.1.8. @hmlanigan

@hmlanigan i have GREAT news that this works fine on juju 3.3 as well

juju deploy k8s jammy-k8s --constraints='cores=2 mem=16G root-disk=40G' --channel=edge --series=jammy --debug

@mcarvalhor it's come to my understanding that juju 3.1 is no longer supported, this is a known bug in juju that seems to have been fixed going forward in supported juju. You are recommended to model migrate to juju 3.3 in order to deploy canonical k8s.

This issue should now remain with k8s in that we should update the metadata of the charm to indicate a required juju 3.3 or beyond
