Proxmox VE No-Subscription Removal

This script removes the 'No valid subscription' warning in Proxmox VE 6 and should only be used in test or demo environments. Please consider buying a subscription and supporting the development of Proxmox VE.

How to install

You can run the removal script one of three ways:

1. Curl

curl into bash like shell:

curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/rickycodes/pve-no-subscription/main/no-subscription-warning.sh | sh

Do not curl blindly 🙈 Audit the script before you run it. It's not doing anything terribly surprising, I assure you!

2. With Git

You can also clone the repo with git and run locally if you prefer, but you'll need git (a typical proxmox host doesn't have it installed):

git clone git@github.com:rickycodes/pve-no-subscription.git
cd pve-no-subscription
bash no-subscription-warning.sh

3. Download

Or, you can download the source directly from one of the releases:

wget https://github.com/rickycodes/pve-no-subscription/releases/download/v1.0/source.tar.gz
tar -xf source.tar.gz
bash ./pve-no-subscription/no-subscription-warning.sh

Diagnostic

The script provides stdout and verifies a few things on behalf of the user.

After a successful run, you should see the following result:

subscription status: NotFound
performing replacement in /usr/share/perl5/PVE/API2/Subscription.pm...
restarting services...
all done!

Running the script a second time will produce the following result:

cannot find item. have you already run the replacement?

Running the script on a non pve install will produce:

/usr/share/perl5/PVE/API2/Subscription.pm does not exist! are you sure this is pve?

TL;DR

If you don't care about the above diagnostic feedback and you'd rather yolo, this is the gist of it:

#!/bin/sh
set -ex
sed -i "s/NotFound/Active/g" "/usr/share/perl5/PVE/API2/Subscription.pm"
systemctl restart pvedaemon
systemctl restart pveproxy

Adding apt hook

After updating you may find you need to re-run the script to apply the patch. You can automate this by adding a Post-Invoke apt hook.

First, let's create the script to run (you can put these files anywhere, but I am following pve conventions as best I can).

touch /usr/share/proxmox-ve/pve-apt-post-hook

The above file should look something like this:

#!/usr/bin/env bash
set -ex
curl --proto '=https' --tlsv1.2 -sSf https://raw.githubusercontent.com/rickycodes/pve-no-subscription/main/no-subscription-warning.sh | sh

We'll also need to make the file executable:

chmod +x /usr/share/proxmox-ve/pve-apt-post-hook

Once that's done, we can add the hook. For that we're going to edit an existing file: /etc/apt/apt.conf.d/10pveapthook

Add the following line to the above file:

DPkg::Post-Invoke { "/usr/share/proxmox-ve/pve-apt-post-hook"; };

And that's it! The next time you perform an apt upgrade you should see something like the following (if the patch needs to be applied):

...
Setting up dnsutils (1:9.11.5.P4+dfsg-5.1+deb10u2) ...

+ sh
+ curl --proto =https --tlsv1.2 -sSf https://raw.githubusercontent.com/rickycodes/pve-no-subscription/main/no-subscription-warning.sh
		status => "NotFound",
subscription status: NotFound
attempting replacement in /usr/share/perl5/PVE/API2/Subscription.pm...

all done!

You can see the script ran successfully around the + sh part.

Notes

I couldn't get the install steps in pve-no-subscription to work properly and discovered this. This script is a result of that discovery.

pve-nag-buster does the replacement in the web UI source, but that approach also seems to have stopped working? There's an issue here with details on how to get around that).

This is very likely to break in the future. But as of this writing it works for proxmox versions 6.2.x through to 7.3-3
