SHA 256 checksum

English Install/Boot/Login

I have downloaded Opensuse Leap 42.1 DVD about six different times now, and from multiple different mirrors, including via bit torrent download (3 times), and I keep getting the SHA256 checksum: 8576E84822CDBE566BF551E28A169FC028229831EBA9F07A4C1F84302C5DDB09 This is not the correct checksum quoted in the download area on the internet. Has there been an update which has changed the checksum? Can I get someone to send me a ready to use DVD, since I can not seem to get an uncorrupted copy?

Any ideas?

I am getting the same checksum as you are getting.

Well, okay, I didn’t compare every digit. If you want to compare, I am getting

8576e84822cdbe566bf551e28a169fc028229831eba9f07a4c1f84302c5ddb09  openSUSE-Leap-42.1-DVD-x86_64.iso

That’s also the sha256 checksum that I am seeing on the download site. I’m wondering how you are checking that site?

Wrong forum for Technical questions, moving to install/boot/login, temporarily closed.

Moved and re-opened.

Obviously the wrong way! I clicked on ‘SHA256Checksum’ at the top right of the download site. This gave me a file: openSUSE-Leap-42.1-DVD-x86_64.iso sha (or very similar). I put this through MD5 and SHA checksum utility which I have on windows 8.1 and got:015407E4314C2EDB9FE86F46EAAD0787C2F60803A3729E0DA617863F3A83A148. That is not what I got when I downloaded openSUSE-Leap-42.1-DVD-x86_64.iso. I thought it must be the download: that it had become corrupted, but obviously I have made some erroneous assumption elsewhere.
Anyway: thanks very much for the information; it indicates that my downloads (probably even the first one!) were OK.
Thanks

That file should have the name: openSUSE-Leap-42.1-DVD-x86_64.iso.sha256

The sha256 checksum is actually on a line in that file. You just had to read the file. Or you do:

sha256sum -c openSUSE-Leap-42.1-DVD-x86_64.iso.sha256

which should do the check for you (assuming that the DVD iso is in the same directory).

The output also has some noise because of the GPG signature. If you are a GPG user, you can check that, too, with:

gpg --verify openSUSE-Leap-42.1-DVD-x86_64.iso.sha256

In any case, it looks as if you have a good download.

Thanks again. I have been trying to migrate to a Linux based system for some time. The first attempt was using a friend’s (I think corrupted) version of Ubuntu. (I forget which version) Needless to say that turned out to be disappointing. My main laptop is a Toshiba with an intel core i7 CPU and 16GB RAM, but it is running Windows 8.1. Not that I intended it to upgrade itself to 8.1: Bill Gates’s automatic updates did that, and I cant use Google Chrome anymore! Still I have disabled the auto updates, so that’s the end of that sort of thing. I am still not confident enough to try a dual boot with Leap 42.1 on the Toshiba. I do have Ubuntu Mate running on an old Compaq Presario. That is quite impressive. The lightweight operating system fairly makes the old thing fly. I have released that I need to get some training in Linux. At the moment I am still exploring the terminal on the Compaq. (Where it doesn’t matter too much if I really foul things up)
I had to download the iso file onto the Toshiba, because the optical drive on the Compaq is not able to burn DVDs. I did not try to read the sha256 file on the Toshiba, because it runs (I assume) some version of DOS.
Anyway: thanks again for the help.
