Etcher doesn't like this image, gives no feedback on why.

I have been preparing Raspberry Pi images in this manner (Ubuntu 16.04):

• SD card with expanded filesystem into the computer.
• Shrink EXT4 partition with GParted
• parted <sd card device> -s print to find End of ext4 partition in MB
• dd bs=1M count=#from parted+1
• right click resulting .img file in nautilus and click compress…zip

Now I have a .img.zip file, etcher has been perfectly happy with these *.img.zip files except for one.

This is the .img.zip file in question. When I select this file from the file browse dialog, etcher behaves as if I had pressed ‘cancel’. It returns to the main ui, it still says ‘select image’, and it gives no feedback on why the image I selected is not showing up. When I unzip this file, etcher lets me select and writes the resulting .img normally, and it functions normally in the Pi afterward. I have also tried compressing the image from the command line using zip with the same results.

Here is another .img.zip prepared in the same manner, that works as expected.

Reminds me of the “dinosaur error” we had with lzma a while back 😉

Turns out this was an upstream bug that has already been fixed in a newer version, so updating to node-stream-zip to 1.3.7 in https://github.com/resin-io/etcher/pull/1730 will fix this.
