Bad zip file download? #1

Closed rotmgkillroyx closed 10 years ago

rotmgkillroyx commented 10 years ago

I'm sorry, but I've been unable to extract the coder_v.4.zip without errors:

wget http://storage.googleapis.com/coder-images/coder_v0.4.zip unzip -a coder_v0.4.zip [snip] inflating: coder_v0.4/raspi.img [binary] error: invalid compressed data to inflate [snip]

7zip also complains about the raspi.img portion, when extracting.

Is this an error I can safely ignore?

Thanks!

Both files (zip and img) work fine for me. The zip file probably got broken during transferring. Here's the SHA1 digest for my zip file: 913c940df9308fcff50978246594ae048c6be476, maybe you could check if you had an authentic file (you could use openssl sha1 /full/path/to/file to check the SHA1 digest).

Yep: openssl sha1 coder_v0.4.zip SHA1(coder_v0.4.zip)= "b7b367de07a8e7a24d66bb59e9b2e6127b39d622"

Well, I'll download it again. Thanks for the hash--that helps. Also, I did try installing the .img anyway, and it crashes to a KB> prompt. Maybe my re-download will work.

AH, looks like there is some bad replication on the google storage side. Downloading from a zone with IP addresses like: 173.194.46.75 gave me corrupted files. However, downloading from 74.125.239.106 gave me a different SHA file. (I had to edit my /etc/hosts to force this DNS mapping.) Now my error is:

inflating: coder_v0.4/raspi.img [binary] bad CRC b73f158e (should be 3e0e311d)

Just a followup on this--I downloaded using WGET on windows and the file was able to be successfully extracted. Closing, I guess.
