OK I upgraded to 3.17.2 now I have a new Error:

Instanz allison.dc2.tcsoc.net: undefined method `include?’ for nil:NilClass config_cpu = config.select { |key, _value| config_typed_keys(type)[:cpu].include? key } ^^^^^^^^^

Any help would be appreciated

Hi @kagouros ,

It’s probably worth filing an issue to Issues · theforeman/foreman_fog_proxmox · GitHub

@nadjaheitmann have you seen this issue before with the proxmox plugin?

We currently have some issues with foreman_fog_proxmox and Foreman 3.17+ which all show similar symptoms. We are on it.

Any news on this. It is failing in a different way since the last upgrade.

6

Can you share which version you are now at how it is failing?

7

Foreman is 3.17 the error I get is the message:
Fehler beim Erstellen einer Rechenressource maxwell (Proxmox) Instanz xx.xx.xx.net: undefined method `include?’ for nil:NilClass config_cpu = config.select { |key, _value| config_typed_keys(type)[:cpu].include? key } ^^^^^^^^^

Proxmox is 9.1.16

9

I mean which foreman_fog_proxmox version are you using?

10

As I install with apt it is:

ruby-foreman-fog-proxmox/plugins,now 0.22.0-1~fm3.17 all [installed]

11

And it is still failing? Hm… Did you try rerunning foreman-installer and restarting the foreman service?

12

Yes i restarted due to other foreman package updates. As the error message changed i do think the new version war properly applied

13

Could you also try and clear your browser cache for the page? I think it is ‘Ctrl + Shit + R‘ or so. Just to make sure you really don’t have any artifacts of the old version lying around.

14

Yes I tried

We are using cpu type passthrough on the proxmox host. And I just retested with the new proxmox 9.2.2 same error.

15

Too bad! Can you please open an issue in Issues · theforeman/foreman_fog_proxmox · GitHub with an exact reproducer.

The issue should be fixed with foreman_fog_proxmox version 0.23.0.
