UI: Unable to deploy CentOS7 - centos/focal not a supported combination

[Wayne]

Attempting deploy CentOS7 thru web console results in error 'contos/focal is not a supported operating system and release combination. Attempting CentOS8 succeeds with error 'One machine cannot be deployed. To proceed, update your selection'

Deploy of default OS 'centos' succeeds in deploying CentOS7 via python-libmaas

MAAS version is 3.1.0 installed via snap on 1/5

[Christian Grabowski (cgrabowski)]

Hi there, can you provide steps to reproduce? After a fresh image sync, I was able to deploy Centos7 on 3.1.

[Wayne (wgoodric)]

Commission a new machine in web interface
Start deploy in web interface with selection OS = CentOS Release = CentOS 7

[Christian Grabowski (cgrabowski)]

Hmm still not able to reproduce. Can you provide the output of `maas $PROFILE boot-resources read`?

Hi, could you please attach regiond.log and rackd.log from around the time when the issue happens?

[Wayne (wgoodric)]

Logs attached, grabbed right after an attempt that generated same error

[Alberto Donato (ack)]

Thanks, could you please also attach the output for `maas $profile machine read $system_id` for that machine?

[Wayne (wgoodric)]

Attached machine read output

[Alberto Donato (ack)]

Could you please perform this test:

1) open the browser inspector
2) reload the maas UI
3) select to deploy the machine with centos
4) in the network tab of the inspector, find the websocket connection request (you can filter by the WS type, there should be only one active)
5) in the response section, there should be a number of request/responses over the WS connection including one request for the "machine.action" deploy action, which looks something like this:

{"method":"machine.action","type":0,"params":{"action":"deploy","extra":{"osystem":"centos","distro_series":"centos70","hwe_kernel":""},"system_id":"w4qyr6"},"request_id":22}

Could you please paste the content of the request in your case?

[Wayne (wgoodric)]

{'type': 0, 'request_id': 15, 'method': 'machine.action', 'params': {'action': 'deploy', 'system_id': 'wkm8sd', 'extra': {'hwe_kernel': '', 'osystem': 'centos', 'distro_series': 'focal'}}}

[Alberto Donato (ack)]

It looks like the UI is passing the wrong distro_series for some reason.

[Caleb Ellis (caleb-ellis)]

Hi there, are you able to check whether deploying is successful if you change the release to CentOS8 then back to CentOS7 without closing the form? The issue might be with the form initialisation.

Also, similarly to the above with the `machine.action` websocket request, there should be a request for `general.osinfo` that looks like:

{"method":"general.osinfo","type":0,"request_id":8}

Are you able to paste the contents of the response? It should have a type of "1" and a request_id that matches the original "general.osinfo" request_id.

[Wayne (wgoodric)]

That fixed it. I had to change tabs and then back to settings to make it take

{"method":"general.osinfo","type":0,"request_id":4}

I couldn't get it to populate any real info about the OS here

[Caleb Ellis (caleb-ellis)]

Sorry, I wasn't clear in my initial message now that I've reread it (apologies). You've provided the request message but I'm looking for the response message, which will have the same request_id (in your case that would have been 4) but a type of 1 (instead of 0). It should look something like:

{
  "type": 1,
  "request_id": 8,
  "rtype": 0,
  "result": {
    "osystems": [
      ["centos", "CentOS"],
      ["ubuntu", "Ubuntu"]
    ],
    "releases": [
      ["centos/centos70", "CentOS 7"],
      ["centos/8", "CentOS 8"],
      ["ubuntu/bionic", "Ubuntu 18.04 LTS \"Bionic Beaver\""],
      ["ubuntu/focal", "Ubuntu 20.04 LTS \"Focal Fossa\""]
    ],
    "kernels": {
      "ubuntu": {
        "bionic": [
          ["ga-18.04", "bionic (ga-18.04)"],
          ["ga-18.04-lowlatency", "bionic (ga-18.04-lowlatency)"],
          ["hwe-18.04", "bionic (hwe-18.04)"],
          ["hwe-18.04-edge", "bionic (hwe-18.04-edge)"],
          ["hwe-18.04-lowlatency", "bionic (hwe-18.04-lowlatency)"],
          ["hwe-18.04-lowlatency-edge", "bionic (hwe-18.04-lowlatency-edge)"]
        ],
        "focal": [
          ["ga-20.04", "focal (ga-20.04)"],
          ["ga-20.04-lowlatency", "focal (ga-20.04-lowlatency)"],
          ["hwe-20.04", "focal (hwe-20.04)"],
          ["hwe-20.04-edge", "focal (hwe-20.04-edge)"],
          ["hwe-20.04-lowlatency", "focal (hwe-20.04-lowlatency)"],
          ["hwe-20.04-lowlatency-edge", "focal (hwe-20.04-lowlatency-edge)"]
        ]
      }
    },
    "default_osystem": "ubuntu",
    "default_release": "focal"
  }
}

I'm mainly wondering if the default_osystem and default_release are being set correctly
