Proxmox seems to use outdated cloud-init Module

[nicolaeser]

Hi,


I wasn’t sure where to report this issue, so I’m writing here.


I’m using Cloud-Init with a Debian VM, and on each startup I see the following console message:
[ 23.822737] cloud-init[458]: 2025-07-31 15:54:32,614 - ug_util.py[WARNING]: DEPRECATED: 'user' of type string is deprecated and will be removed in a future release. Use 'users' list instead.

After some research, I found that there are files in /var/lib/cloud containing the user configuration. As far as I know, Proxmox generates these files. My Cloud-Init configuration doesn’t contain any user entries elsewhere.


It seems that Proxmox might still be using the old user format instead of the users list — or am I mistaken? If this is the case, where should I report it?


Best regards,
Nico Laeser

I am seeing this deprecation warning as well, and noticed that the deprecated `user` configuration is present in the output of qm cloudinit dump <vmid> user. The Proxmox Cloud-Init Support documentation indicates that this command can be used to obtain the cloud-init config that is automatically generated by Proxmox to be used as a base for custom cloud-init config.

On the Debian 13 cloud image (which includes cloud-init 25.1.4) the error message says that this deprecated key will be removed in cloud-init 27.2. Hopefully this config will be updated by 2027!

I am still running Proxmox 8.4.2, but I didn't see anything cloud-init related in the Proxmox 9.0 release notes.
