ORIGINAL POST Proxmox VE nag removal, manually

---

This is a rudimentary description of a manual popup removal method which Proxmox stubbornly keep censoring. ^

TIP You might instead prefer a reliable and safe scripted method of the “nag” removal.

Fresh install

First, make sure you have set up the correct repositories for upgrades.

IMPORTANT All actions below preferably performed over direct SSH connection or console, NOT via Web GUI.

Upgrade (if you wish so) before the removal:

apt update && apt -y full-upgrade

CAUTION Upgrade after removal may overwrite your modification.

Removal

Make a copy of the offending JavaScript piece:

cp /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js{,.bak}

Edit in place around above line 600 and remove the marked lines:

--- proxmoxlib.js.bak
+++ proxmoxlib.js

     checked_command: function(orig_cmd) {
    Proxmox.Utils.API2Request(
        {
        url: '/nodes/localhost/subscription',
        method: 'GET',
        failure: function(response, opts) {
            Ext.Msg.alert(gettext('Error'), response.htmlStatus);
        },
        success: function(response, opts) {
-           let res = response.result;
-           if (res === null || res === undefined || !res || res
-           .data.status.toLowerCase() !== 'active') {
-           Ext.Msg.show({
-               title: gettext('No valid subscription'),
-               icon: Ext.Msg.WARNING,
-               message: Proxmox.Utils.getNoSubKeyHtml(res.data.url),
-               buttons: Ext.Msg.OK,
-               callback: function(btn) {
-               if (btn !== 'ok') {
-                   return;
-               }
-               orig_cmd();
-               },
-           });
-           } else {
            orig_cmd();
-           }
        },
        },
    );
     },

Restore default component

Should anything go wrong, revert back:

apt reinstall proxmox-widget-toolkit
