Howdy,
https://www.olimex.com/wiki/Prebuilt_SD_card_images_running_debian#Debian_with_GUI_.28X.29
points to several versions on images someone was creating for running Debian on the Olinuxino. I have downloaded almost all of them and they are all corrupt. Most are zip files and zip files record checksums of the included files. After downloading, I run unzip -t <name of download> and I get notified the the crc is not right. I have downloaded files multiple times and the errors and crcs are consistent. So, I most likely have a good download I also tried this with version 17 and 18 which I guessed to exist based on forum posts, but are not listed on the wiki page.
Have a good day
I think you'll find they are NOT corrupt but rather that your system cannot properly process them!
Someone broke Ubuntu/Debian or the like.
Either process them on a different computer or with working software (maybe 7zip? maybe statically linked unzip? etc).
I hit the same problem and fixed it using unzip on an x86 with an old Linux distro. I posted about this on here.
