[SOLVED] Can't unpack Norns Disk Image pre-211028 shield

I am trying to load the pre-211028 shield onto my DIY Norns.

I successfully downloaded the 211028 shield disk image and unpacked, loaded it on a SD card with the ETCHER, “JACK FAIL”
Must have a 4270 not a 4271.
So I am trying to load the pre-211028 shield.
Downloads okay, comes with a second file: (norns220306-shield-pi3-cs4270.yPfnv0J9.tgz.part)
When I try to unpack it, with Archive Utility (Mac) Unable to expand, unknown format.

Obviously I am missing some important piece if information.

The Important piece of information: Firefox tried to download the file in 2 parts. I don’t know why. I used Chrome, no problems.

Any help appreciated.

hmmm. I’m not sure, but I think the problem is the two files. There should only be one.

I believe this is a Firefox feature, it’s not downloading in two parts, it’s creating a .part file to be able to resume a download if it’s interrupted. The .part file should disappear when the file download is complete.

Are you good with the image you downloaded via chrome?

seems pretty clear, it was an incomplete download from firefox.


Yes, when I discovered that Firefox is the usual culprit in the PART downloaded file extension, I changed to Chrome and it downloaded quick and perfect. Thank you all, my very silly mistake.
