Bug description

Note: I've checked "Nextcloud Server is up to date" but it isn't (given that it is a requirement for reproducing this issue): it's at 30.0.8.

I have set 'updatechecker' => false on config.php, but I'm still getting update notifications by email and in the web interface. My expectation, given the documentation, is that Nextcloud shouldn't even check for updates:

Check if Nextcloud is up-to-date and shows a notification if a new version is available. It sends current version, php version, installation and last update time and release channel to the updater server which responds with the latest available version based on those metrics.

Possibly related, but without replies: https://help.nextcloud.com/t/notification-of-update-still-visible-after-an-upgrade/193531

Possibly relevant code paths:

if ($config->getSystemValue('updatechecker', true) !== true) {

if (!$this->config->getSystemValueBool('has_internet_connection', true)) {

Steps to reproduce

  1. Install an outdated Nextcloud version (e.g., 30.0.8)
  2. Set 'updatechecker' => false, on config.php
  3. Wait for "new update available" notification

Expected behavior

Nextcloud should not check for updates, or at least not send notifications if updatechecker is set to false.

The has_internet_connection option seems to disable the update checker for good, but if I'm not mistaken is also disables other features.
