Call to undefined method OC\Server::getContentSecurityPolicyNonceManager() (Owncloud no longer supported?)

[ted-strauss-K1]

Expected behavior

Go to step 2 of plugin installation.

Actual behavior

Owncloud crashes after cloning this plugin into the apps directory.
owncloud.log throws this error:
Error: Call to undefined method OC\Server::getContentSecurityPolicyNonceManager()

I checked the current OC core, and there is no function with that name.
Is there an earlier version of this plugin that might still work with OC?
Is there a workaround to this missing function? Thanks

Steps to reproduce the behavior

1. Following installation instructions ...
2. Cloned this repo into folder piwik into owncloud/apps/
3. Refresh OC web, shows error screen and writes error logs.

Environment

• App version:

Latest commit f32be86

• Nextcloud version:

Owncloud version 10.0.10.4

• Browser vendor and version:

• Any browser plugins enabled?

Yes. Owncloud support was silently removed in 0.4, because after the split, I had the feeling that there was no love from Owncloud for app developers. So I stopped supporting Owncloud in all my applications.

If you like you can try to remove the corresponding section in

cloud_piwik/appinfo/app.php

Lines 18 to 26 in 0f83f50

	$policy = new OCP\AppFramework\Http\ContentSecurityPolicy();
	if ($url !== false && array_key_exists('HTTP_HOST', $_SERVER)
	&& $_SERVER['HTTP_HOST'] !== $url && !empty($url)) {
	$policy->addAllowedScriptDomain($url);
	$policy->addAllowedImageDomain($url);
	\OC::$server->getContentSecurityPolicyManager()->addDefaultPolicy($policy);
	}

you might want to update this page since it still advertises the app as being intended for OC.

Thanks for the hint. I will update the page asap.
