Comment 9 for bug 1964815

Looking at the metadata associated with the published charm, the series is wrong.

    series:
    - focal
    - panther

That's why juju is complaining about the only supported series being focal or panther.

This means that the charm has been incorrectly packed with an incorrect charmcraft manifest file.

$ juju info slurmd --format yaml
type: charm
id: PNY1jWPbggzG1NZvpftYqLgg86qKyNtd
name: slurmd
description: |
  This charm provides slurmd, munged, and the bindings to other utilities
  that make lifecycle operations a breeze.

  slurmd is the compute node daemon of SLURM. It monitors all tasks running
  on the compute node, accepts work (tasks), launches tasks, and kills
  running tasks upon request.

  Slurmd, the compute node daemon of Slurm.
series:
- focal
- centos7
store-url: https://charmhub.io/slurmd
charm:
  config:
    options:
      custom-slurm-repo:
        type: string
        description: |
          Use a custom repository for Slurm installation.
          This can be set to the Organization's local mirror/cache of packages and supersedes the Omnivector repositories. Alternatively, it can be used to track a `testing` Slurm version, e.g. by setting to `ppa:omnivector/osd-testing` (on Ubuntu), or `https://omnivector-solutions.github.io/repo/centos7/stable/$basearch` (on CentOS).
          Note: The configuration `custom-slurm-repo` must be set *before* deploying the units. Changing this value after deploying the units will not reinstall Slurm.
        default: ""
      nhc-conf:
        type: string
        description: |
          Custom extra configuration to use for Node Health Check.
          These lines are appended to a basic `nhc.conf` provided by the charm.
        default: ""
      partition-config:
        type: string
        description: |
          Extra partition configuration, specified as a space separated `key=value` in a single line.
          Example usage: $ juju config slurmd partition-config="DefaultTime=45:00 MaxTime=1:00:00"
        default: ""
      partition-name:
        type: string
        description: |
          Name by which the partition may be referenced (e.g. `Interactive`).
          Note: the partition name should only contain letters, numbers, and hyphens. Spaces are not allowed.
      partition-state:
        type: string
        description: |
          State of partition or availability for use. Possible values are `UP`, `DOWN`, `DRAIN` and `INACTIVE`. The default value is `UP`. See also the related `Alternate` keyword.
        default: UP
