Updating Proxmox VE

NOTE: At the time of writing I am using Proxmox VE 6.x
These instructions may no longer apply to future versions of Proxmox! Check the Proxmox documentation out before you try this!

Overview

These instructions are really for my own use (to prompt my terrible memory!) but allow you to update the base OS of Proxmox.

Steps

• SSH to your Proxmox VE host.

• Add the following to /etc/apt/sources.list:

# Debian

deb http://ftp.uk.debian.org/debian buster main contrib

# Security

# Proxmox

Note that you might want to change the uk in the Debian.org URLs above.

apt dist-upgrade
