wp core upgrade failed

Is anyone else getting a “wp core upgrade failed” when trying to UPDATE wordpress SCRIPTS using the gpl version?

I get:

Now upgrading WordPress to version 4.9.4 in 27 locations …
Installing in domain example.com
Configuring webserver PHP settings …
… already done.
wp core upgrade failed :
… done

Is there a way to manually upgrade wordpress?

No one?

Is no one having this problem?
