You were right about 0.07 and generic-legacy. Screenshots are from the x64 and the rpi3 installations. I updated them to 0.08 and I am waiting for tomorrow.
As for the mediafire link. Wget-ing it results in an html file. I named it "whatever" because the redirections that wget has to go through add my public ip to it
$ wget https://download1322.mediafire.com/7yyjs05bvw0g/xp2d64y5k06skp4/get_nightly.sh -O whatever

Having said that, I offer to add it as a gist and I (promise that I) will keep updating with every new release that you make.
It leads to the raw text version of the gist, so one can use it with wget directly.

---edit
I can now confirm that v0.08 works properly on generic-legacy. I just noticed a new image was uploaded earlier today, so I made the upgrade via the script.
