VE 9 - Unable to create Debian 13 container

[HomelabPenguin]

A fresh install today of PVE 9 with updates installed (no subscription yet), and I am unable to create a container based on Debian 13. Everything I found mentions a variant of this error has been fixed 8 days ago.

Is this another known issue? Is there a solution? Thank you!

The system has been updated prior to attempting this.



1. Download the CT Template


2. Create a new container



3. Receive Error

Looks like your Proxmox is still not up to date. What is the output of pveversion -v and apt update?

You need a paid support subscription to use the enterprise repositories. Alternatively, switch to the no-subscription repositories instead (same functionality and you'll get updates and fixes sooner): https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_package_repositories? Lots of threads about this on this forum.

Ahh I missed that as I am going to purchase a subscription and didn't bother looking for alternatives. Thank you!!

One more thing: never run apt upgrade on Proxmox. Use apt dist-upgrade instead: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#system_software_updates
