Update Version 1.0.21 to Version 1.0.22 get inconsistant file permissions

I am trying to update WP-MATOMO v 1.0.21 to v 1.0.22.
After clicking up the update link, I get the following error.

What file are causing this issue?

Thanks for your help in advance

Hi,

Honestly that looks like a issue with your wordpress setup. Can you check if all permissions are set correctly?

But I know little about Wordpress, maybe @WP_PiwikDev can help.
