Tutorial: Remove Proxmox Subscription Warning

Note about Proxmox repositories:
Proxmox provides different package sources (repositories):

• Enterprise Repository → requires a valid subscription, stable & recommended for production use
• Community Repository → free to use, ideal for homelabs & test environments

Even without a valid subscription you can fully use Proxmox – including the Community Repository.
The following tutorial only shows how to remove the warning message in the web interface.

When Proxmox is used without a valid subscription, the well-known "No valid subscription" message appears when logging into the web interface.
For production environments the Enterprise subscription is recommended, but in homelabs or test setups the warning is usually just annoying.

With a small tweak you can remove it permanently.

Step-by-step guide

1. Create a backup & apply the patch

sed -Ezi.bak "s/(Ext.Msg.show\(\{\s+title: gettext\('No valid sub)/void\(\{ \/\/\1/g" \
/usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js

👉 This command comments out the section that generates the message.
A backup file (.bak) will automatically be created.

2. Restart the Proxmox proxy

systemctl restart pveproxy.service

3. Refresh the web interface

• Reload the browser (best with cache cleared / Ctrl+F5)
• The warning should now be gone 🎉

Conclusion

With just two commands you can remove the Proxmox subscription notice.
For production environments, however, the Enterprise Repository is still recommended.
For homelabs and test setups, the Community Repository is the better choice – and completely free to use.
