Removing the Proxmox VE subscription notice

Proxmox VE’s web UI shows a “No valid subscription” dialog on every login when the node has no paid subscription key registered. This is a cosmetic nag, not a functional limitation — the following patch suppresses it. Tested up to Proxmox VE 8.3; reapply after any update that touches the proxmox-widget-toolkit package.

Prerequisites

• SSH or web-UI shell access to the node as root.

Steps

1. Patch proxmoxlib.js

sed -Ezi.bak "s/(function\(orig_cmd\) \{)/\1\n\torig_cmd();\n\treturn;/g" /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js && systemctl restart pveproxy.service

This edits the function that normally checks subscription status before running the originally requested UI operation, making it run the operation immediately and return, skipping the check entirely. A .bak backup of the original file is created automatically (the -i.bak flag).

2. Clear your browser cache

The web UI caches proxmoxlib.js client-side — open a new tab or restart the browser (or hard reload) for the change to take effect.

Verify

Log into the Proxmox web UI again — the subscription dialog should no longer appear.

Troubleshooting

• Notice reappears after an update: any update that reinstalls proxmox-widget-toolkit overwrites the patched file — reapply the one-liner.

Reverting

Three ways to undo the change:

1. Restore the automatic backup:

   mv /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js.bak /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js

2. Reinstall the package fresh from the repository:

   apt-get install --reinstall proxmox-widget-toolkit

3. Manually re-edit proxmoxlib.js to remove the inserted lines.
