Upgrade ProxmoxVE 6.1 to 6.2 without Subscription

Once you have SSHed into your Proxmox:

cd /etc/apt/sources.list.d/

There, you should find two files, pve-enterprise.list and pve-no-subscription.list.

To make sure that you don't pull anything off the enterprise version, comment out the text in pve.enterpirse.list .

Now, in pve-no-subscription.list make sure that you have the following line:
deb https://download.proxmox.com/debian/pve buster pve-no-subscription
Save and exit the file.

Also, just to make sure that we are on the same page, if you check ../sources.list you should have three urls. There you should see:

  • buster main contrib
  • buster-updates main contirb
  • buster/updates main contrib

Try running :

apt update && apt dist-upgrade

After that ends, you will need to reboot. However, in order to reboot, make sure that there are no virtual machines running.


And, when it boots up, you should have Proxmox 6.2
