Can't unzip SD card image


I’m trying to unzip the image found here:

I’ve downloaded it twice. The current (zipped) file is 7.58GB and SHA256 is:

Both times, unzipping (by double clicking on Mac Finder) results in a *.cpgz file. Trying the “unzip” command in Terminal gives this error:

$ unzip
warning []: 3285468411 extra bytes at beginning or within zipfile
(attempting to process anyway)
error []: start of central directory not found;
zipfile corrupt.
(please check that you have transferred or created the zipfile in the
appropriate BINARY mode and that you have compiled UnZip properly)

I am going to use Balena Etcher (on Mac)- I’ve seen vague references to just imaging the zip file directly to the SD card - is this the correct method?

Thank you.

I think I figured it out - I tried just flashing the ZIP file directly to the SD card, using Balena Etcher, and it appears to work.

I can now SSH into the Nano and the Jupyter login page loads over USB connection, however the default password is not working in Firefox or Safari (could be one of several blockers/cookie restrictions).

For those who are curious - I just opened in Etcher, and it automagically changed the extension to “.img”. I didn’t do any manual unzipping at all.

It would be helpful if they’d make that a little more clear in the tutorial -

Any advice on getting the Jupyter login to work now???
