Could not determine target sites directory

[martinfrances107]

while using this again today after a break.. all my images and volumes had been deleted,
so I had cause to run

.dropwhale/reset.sh

I am posting the output below, it looks like the drush "site install" task is failing
in the last 3-4 months I think I saw a critical update -- some command line parameters
are now essential...

I create a PR when I track this down...
