Hey I just noticed myself that changing the file in /etc/apache2/sites-available and change the root folder i’m able to change back to wordpress directory, but subdirectory links (of my multisite) no longer working, plus it should be working on Nginx as before the update.
The output of sudo netstat -tnlp and sudo service nginx status:
