Requires small fix.

Here are details.

Also it seems that upgrade removed zend user:
sudo /usr/local/zend/bin/zendctl.sh restart
id: zend: no such user
id: zend: no such user
id: zend: no such user
id: zend: no such user
id: zend: no such user
id: zend: no such user
id: zend: no such user
id: zend: no such user
id: zend: no such user
id: zend: no such user
zdd is not running

So reinstall is in order anyway :-(
