Re: verifying iso images downloaded by jigdo during installation [SOLVED]

[Mohammed El-Afifi <mohammed_elafifi@xxxxxxxxx>]

Thank you all for your suggestions. Kanarip, the person in charge of producing re-spins in fedoraunity, has responded to my request and has posted a page on the fedoraunity site containing SHA1SUM calculated for all fedora 9 everything re-spins. The page URL is http://us.mg2.mail.yahoo.com/dc/launch?sysreq=ignore, just in case anyone needs it.
Thanks again for your active feedback.

The problem is that there's no single site the iso is downloaded from. Jigdo works by downloading single package files from several sites(mirrors) and then accumulating them into a single iso file. I downloaded the jigdo file(the file containing information about the iso images) form the fedoraunity website, however there were no SHA1SUM for these ISO images at that site.

I posted a request on the fedoraunity site so that they may publish the SHA1SUM for these images. If anyone knows where such SHA1SUM files for these images may exist, it would be greatly helpful.

If anyone also has downloaded DVD 2 of that re-spin, he/she may try to test it against the verification step in the installation process. You don't have to perform a real installation to verify the media, just boot a computer and wait till you get into the verification step. If it passes, please calculate the SHA1SUM for the image and post it.

Otherwise, I'm afraid I may have to re-download the the suspected iso image again, which may take a few other days.

You can verify using the sha1 text file provided at the download site:
sha1sum file.iso | grep -f sha1.txt.
You should be able to see sha1sum signature after this operation. If a blank line is retuned, means your download image is bad. The above operation takes a long time depending on your system's speed.

I'm downloading the DVD iso images for fedora 9 everything 64-bit using jigdo. This spin comes in 4 DVD's. I've finished downloading the first two DVD iso images completely. I then tried to install fedora 9 and booted my computer using the first DVD.
Before starting anakonda installer, I've the chance of verifying the installation media. When I was prompted for verification, I chose to verify the two DVD's I've till now. Actually, this was the sole purpose of running the installation DVD, to verify the images I downloaded so far.
Everything went all right with DVD 1, however DVD 2 was reported to have errors. I tried to verify DVD 2 using jigdo-file and the template file for DVD 2, and jigdo-file reported that the image is good.
The problem can't even be with my DVD burner, because I haven't burned the images yet. I used VMWare instead to boot a 64-bit virtual machine using the iso files.
So now DVD 2 is reported to have errors by the verification step in the installation process, while jigdo-file reports no errors about the image.
Are all the installation media of the everything spin of fedora 9 64-bit guaranteed to pass the verification process during installation or just the first DVD(probably because it may match the official distribution fedora 9 64-bit DVD while the other DVD's aren't part of the official distribution)? Is there a method to verify the image externally(with a third tool for example) to settle if it's good or not?
Appreciating your help.
