These are just a couple of examples. I have reproduced this on my Ubuntu 11.10 laptop, a Ubuntu 11.10 VM running under VirtualBox with a Windows 7 Ultimate Host on a Core i5 Desktop with 8 GB RAM and a OCZ RevoDrive SSD, and as a bare-metal install on a Core i7 Desktop with 16 GB RAM using an OCZ Vertex 3 SSD. That's three separate systems with the only thing in common being Ubuntu 11.10. The Core i7 was running Server edition and the other two were running Desktop edition. I have a fourth system running CentOS 6 which downloads the file correctly every single time. Further, the Windows 7 host downloads the file correctly every single time. When running the Windows 7 host on the Core i7 hardware (by just moving the boot drive over the Core i7 system) it also downloads correctly there every time. The Core i7 system is brand new (arrived in the mail yesterday).
When the SHA1 checksum displays incorrectly, attempting to unpack the download results in gzip complaining about corrupted data and the unpacking fails.
In addition, I have tested using wget, ncftpget, curl, chrome, and firefox. All methods of downloading the file I have tested result in sometimes getting a corrupted file and sometimes getting an uncorrupted file. I have tested 6 different mirrors and gotten both corrupted and uncorrupted versions from all 6 mirrors. When the sha1sum is incorrect, it never repeats any other incorrect checksum. This means it is corrupted differently every time it gets corrupted.
I can provide SSH access to an affected system if someone needs to do hands-on troubleshooting.
