Manual Steps Here are alternative step by step instructions so you can understand what the above command is doing:

  1. Change to working directory
cd /usr/share/javascript/proxmox-widget-toolkit
  1. Make a backup
cp proxmoxlib.js proxmoxlib.js.bak
  1. Edit the file
nano proxmoxlib.js
  1. Locate the following code (Use ctrl+w in nano and search for “No valid subscription”){
  title: gettext('No valid subscription'),
  1. Replace “” with “void”
void({ //{
  title: gettext('No valid subscription'),
  1. Restart the Proxmox web service (also be sure to clear your browser cache, depending on the browser you may need to open a new tab or restart the browser)
systemctl restart pveproxy.service

Additional Notes You can quickly check if the change has been made:

grep -n -B 1 'No valid sub' proxmoxlib.js

You have three options to revert the changes:

  • Manually edit proxmoxlib.js to to undo the changes you made
  • Restore the backup file you created from the proxmox-widget-toolkit directory
mv proxmoxlib.js.bak proxmoxlib.js
  • Reinstall the proxmox-widget-toolkit package from the repository
apt-get install --reinstall proxmox-widget-toolkit
