Before all, I’m not a developer, I have minimum knowledge.

I have a problem in WordPress 5.4 autoupdate. I hosted this CMS in Google Cloud and before this update I had no problems updating it.

My error message is: “The update could not be installed because some files could not be copied. Usually this is due to inconsistent file permissions.: wp-admin/includes/update-core.php”

I need help to give permissions via SSH, because I think is the only way.
