I just got a Udoo Quad recently and went to go download the distribution I intend to use with it, but the zip fails to extract the .img file. In OS X: Archive Utility creates a new .cpgz file. Using Terminal in OS X: `unzip /path/to/file` yields an error: Code: unzip ~/Downloads/udoo_quad_android_1.1.zip Archive: /Users/.../Downloads/udoo_quad_android_1.1.zip warning [/Users/.../Downloads/udoo_quad_android_1.1.zip]: 76 extra bytes at beginning or within zipfile (attempting to process anyway) error [/Users/.../Downloads/udoo_quad_android_1.1.zip]: reported length of central directory is -76 bytes too long (Atari STZip zipfile? J.H.Holm ZIPSPLIT 1.1 zipfile?). Compensating... skipping: udoo_quad_android_1.1.img need PK compat. v4.5 (can do v2.1) note: didn't find end-of-central-dir signature at end of central dir. (please check that you have transferred or created the zipfile in the appropriate BINARY mode and that you have compiled UnZip properly) (username removed for privacy) Using Windows 7 built-in tools: You need an additional 734 PB to extract this file. Using 7Zip in Windows 7: Extracts the .img, but they show an incorrect size and fail to attach as a file system. A 680MB .img shows up as roughly 7GB. I've downloaded the files multiple times and each time the SHA1 hash matches. I've downloaded in Windows 7 (using Chrome) and in OS X (Safari 7.0.1). I've tried the download from SourceForge (preferred because it's quicker), via torrent and the mirror -- I can't extract the .img file. I'm trying to download the Udoo Quad - Android Jellly Bean and the Udoo Quad - Debian Wheezy.
