Debian Testing LXC Template for Proxmox

This is a minimal Debian testing LXC template for Proxmox VE, built by upgrading the official debian-12-standard_12.7-1_amd64.tar.zst container to the current testing release.

Features

• Based on official Proxmox Debian 12 template
• Upgraded to Debian testing (rolling release)
• Cleaned, trimmed, compressed with zstd
• No cloud-init, no unnecessary packages
• Logs, docs, locales, APT cache stripped

Usage

Because of the max 100MB filesize limit imposed by Github I had to upload the template to archive.org.

1. Download the template https://archive.org/download/debian-testing-amd64.tar/debian-testing-amd64.tar.zst

2. Upload the .tar.zst file to your Proxmox node:

   /var/lib/vz/template/cache/
   

3. Create a container from the template from the Proxmox UI, or by using this commandline:

   pct create <vmid> local:vztmpl/debian-testing-amd64.tar.zst --rootfs local-lvm:8 --hostname my-ct

   Adjust <vmid>, storage, and hostname as needed.

⚠️ Notes

• Compressed with zstd -19 --long=27 for Proxmox compatibility
• You can customize further after container creation
• This is not an official template — use at your own discretion

Build Info

Built manually in a chroot using the following steps:

• Extracted base Proxmox Debian 12 LXC template
• Chrooted and upgraded to testing via apt full-upgrade
• Cleaned system and compressed to .tar.zst
