Problem: Following updating a Foreman server from 3.12 to 3.17 (going to each release between!) the Proxmox plugin appears to be broken. Any attempt to add or modify a “Compute Profile” gives the error “Oops, we’re sorry but something went wrong undefined method `identity’ for nil:NilClass”
Expected outcome: I should be able to add or edit Compute Profiles for Proxmox
Foreman and Proxy versions: Foreman 3.17 / Katello 4.19
Foreman and Proxy plugin versions:
foreman-tasks 11.0.6
Distribution and version:

Hi @Gareth , which fog-proxmox version are you using?

Hi, I’m not sure how to tell - it was installed using the foreman-installer. The “About” page shows version 0.19.1 for the foreman_fog_proxmox plugin
You can run ‘rpm -qa | grep proxmox‘ .
Which Proxmox instance version are you using?

nadjaheitmann:
rpm -qa | grep proxmox
Looks like 0.15.2-1:
We are running Proxmox 9.1.1, which I realise isn’t officially supported, but it was working prior to updating Foreman…
We have released a newer plugin version for Foreman 3.17 today. It will be available tomorrow I guess. You can try if that solves the issue. If not, please report back - then we have to keep looking!
You don’t have other compute resource plugins installed besides Proxmox, do you? Maybe ovirt?

I will test installing the latest one on Monday, thank you - what’s the suggested way to update it?
Regarding other computer resource plugins - we do have the VMWare plugin as well, but that’s it.
Personally, I would create a backup, ‘dnf upgrade’ the package, run the foreman-installer and do a ‘foreman-maintain service restart’.
