md5sum and sha1sum don't match

[isadora]

I have downloaded Mageia 3 DVD iso from 3 different mirrors and none of the md5sum or sha1sum match what is on the download web site. What's the problem?

Code: Select all


$>md5sum Mageia-3-x86_64-DVD.iso
1b14e889eb0b99ddf8153fab468f49e7  Mageia-3-x86_64-DVD.iso
$>md5sum ./Mageia-3-x86_64-DVD.iso
eda49855b6fdad555fb53ca2332c67ba  ./Mageia-3-x86_64-DVD.iso

sha1sum ./Mageia-3-x86_64-DVD.iso
f1c4ace8fd537e9029afab8b10bd06341654431b  ./Mageia-3-x86_64-DVD.
>sha1sum ./Mageia-3-x86_64-DVD.iso
1ce7cb423fd426208f200fc538988d3c77ba66c1  ./Mageia-3-x86_64-DVD.iso
$>sha1sum ./Mageia-3-x86_64-DVD.iso

Strange. There is some possibly helpful information in this wiki page.
I always use torrent program to download iso files which check them by design besides lighter load to servers.

I'm suspecting that when ISO images with classical images have been updated, the md5sums on the download page may have been forgotten.
But if you download via torrent, there's also the advantage that you get separate files with the checksums and index files showing packages on the media additional to the iso images. And free checksum testing during download.

Thank you both. I will try the torrent

[leon244]

I tried the torrent. then when done did

Code: Select all

sha1sum -c Mageia-3-x86_64-DVD.iso.sha1

and got a failure

Code: Select all

Mageia-3-x86_64-DVD.iso: FAILED
sha1sum: WARNING: 1 computed checksum did NOT match


Not sure what to do now.

Leon are you sure that your storage media is flawless? Can you verify that with GSmartControl? It's in our repos.

It wasn't.

Not completely sure what you mean by "flawless", but I ran gsmartcontrol and the drive is marked as having Passed the Overall Health Self-Assessment Test.
All my drives are marked as having "Passed" the Overall Health Self-Assessment.
I tried downloading to another drive, but still no sha1 match.

Nice.

Strange.

Can you check your download within torrent program you use? I know that Ktorrent has an right click option "Check data" or something like that.

[leon244]

I will do so when I get a chance. I am also wondering if my download program is having problems. I have been using Vuze, but will try again with KTorrent and check the download. thanks. Will get back when I have a chance.

[doktor5000]

Remember that you don't have to re-download the complete image. Start the download, overwrite the .iso
with the one you have already downloaded and let it re-check the download data. Saves bandwith

[leon244]

Not sure if I did it correctly, but I redownloaded the torrent using Chrome this time and KTorrent for the download. When done I did a "Check data" and there was 1 chunk out of 1878 chunks that failed. I tried two different times and had the same failure. I downloaded to a separate HDD, different from the ones I used before. Still had sha1sum check failure.

Not sure what else to do, but will pursue when I have more time. I have found some issues on Mozillazine about problems with FF but don't have time right now to pursue them. Will also reboot and try again when I have time.
Thanks for you help. Any other ideas are welcome.
