sha1sum does not match listed sum on site

Postby jakebpg » Thu Oct 04, 2012 10:56 pm

I just downloaded the archlinux-hf-2012-09-18.img and the sum that I get after running the following command (sha1sum /mypath/archlinux-hf-2012-09-18.img/archlinux-hf-2012-09-18.img) is way different then the listed sha1sum of(56e043f3c629f6c408759bcc157d2d635ce0b6af).

The returned sha1sum is (fef56565e1098fb91ef93e0c31111119d7cea021) while the one listed on the download site is 56e043f3c629f6c408759bcc157d2d635ce0b6af

So what's going on here?

Is this a valid image file or not!

Is this downloaded image even worth trying since the sha1sum fails the test to match the listed sha1sum listed! As you can see the sha1sums are very different and does bring to light a concern that the .img file is NOT a trusted file by the check sums not matching!

Some one HELP!

Pepedog is this the true file that you were talking about? Why doesn't the sha1sum match?

I ask because I do have some important servers running on my network that I do NOT wish to expose to a system that may not be a valid img file from the ALARM site!

All that remains is someone else to verify what they got from official download.

So strike me very confused. From the official RPi site:

Torrent archlinux-hf-2012-09-18.zip.torrent
Direct download archlinux-hf-2012-09-18.zip
SHA-1 56e043f3c629f6c408759bcc157d2d635ce0b6af

On disk, the sha1sum of the zip file (admittedly torrented (and seeded)) is as advertised. So what's the all alleged problem? That the zip file sha1sum matches the zip file's advertised shasum? Film at 11.

Stron, it's not the zip file but the image file itself! Please reread my original post! Not to mention I didn't use the torrent download.

thanks pepedog, that's all I needed to know for now!

Just as some info, sha1sum on a zip file doesn't mean the underlying files are as they are supposed to be. That is why I asked the question.

Perhaps you could get the sha1sum added to the downloaded file or just have the download page updated with the sha1sum of the actual .img file.

Again thanks for your help.

I've really been looking forward to running the hf version to see how much of a difference it makes on the rpi. I also want to see if it makes a difference on how motion runs. Of course motion is in reference to one of the other tops that I asked about but believe it was on the raspberry pi site.
