3 years ago Update... Since this is a large file archive, I also tries the 7zip utility 7z supplied with Ubuntu 20.04. Here's the output when using 7z john@arach:~/Downloads$ 7z e Sumnode-pi4.img.zip

Please advise the recommended utility for extracting the Pi4 .zip file and provide the output of md5sum, if possible.
The md5sum of my copy of Sumnode-pi-os-v1.img.zip is 4744063b7c073a8a0abbbfb705e884e0 I sued unzip (UnZip 6.00 of 20 April 2009, by Debian.) to extract the .img file to attempt to extract the file. I got this series of errors: john@arach:~/Downloads$ unzip Sumnode-pi-os-v1.img.zip Archive: Sumnode-pi-os-v1.img.zip warning [Sumnode-pi-os-v1.img.zip]: 4294967296 extra bytes at beginning or within zipfile (attempting to process anyway) file #1: bad zipfile offset (local header sig): 4294967296 (attempting to re-compensate) replace Sumnode-pi-os-v1.img?

error: invalid compressed data to inflate error: not enough memory for bomb detection The .img file that was extracted is 4527095808 bytes in size and has an md5sum of d0ba1c13a1cbe906236c07aafc9da6f8
Please advise if this is a valid image, as it appears to be too small to me because the README.md states The Image is 8 GB and will take some time to download.
If the download is hosted elsewhere as well, please advise. I would build from source if the sources are available.
