Download iso always break

vico · November 23, 2025, 8:38pm

I have tried various ways of download

Mirros
Leap’s torrent
Metalinks

Unfortunately my attempts haven’t been successful
Every time I verify by right clicking the ISO (on mint xfce by the way) the result is just not correct
The weird thing is that the result from the ISO seems to for me consistently be: 39c78ebc24eef3d1c7243560a7fc14624820b766cda27a4f8ffab6f8492b2487
instead of the expected result.

Also tried aria2’s aria2c -v command but it doesn’t work for me for some reason.

I can’t quite understand how to fix a ISO so I would enjoy some help.
Thank you in advance

Do you:

save the ISO on a disk with linux filesystem (etx or btrfs or xfs)
compare the downloaded ISO by
sha256sum -c Isoname.iso.sha256

Here I downloded a Leap ISO:

Now the shasum File:

And now the Keyfile

Now I imported the Project’s signing key:

stephan@linux64:~/soundKonverter> gpg --keyserver keyserver.ubuntu.com --recv-keys 0x35A2F86E29B700A4
gpg: Schlüssel 35A2F86E29B700A4: Öffentlicher Schlüssel "openSUSE Project Signing Key <opensuse@opensuse.org>" importiert
gpg: Anzahl insgesamt bearbeiteter Schlüssel: 1
gpg:                              importiert: 1

Now I look for the Signing of the shasum file:

stephan@linux64:~/soundKonverter> gpg --verify Leap-16.0-offline-installer-x86_64-Build171.1.install.iso.sha256.asc Leap-16.0-offline-installer-x86_64-Build171.1.install.iso.sha256
gpg: Signatur vom Mo 29 Sep 2025 20:51:29 CEST
gpg:                mittels RSA-Schlüssel 35A2F86E29B700A4
gpg: Korrekte Signatur von "openSUSE Project Signing Key <opensuse@opensuse.org>" [unbekannt]
gpg: WARNUNG: Dieser Schlüssel trägt keine vertrauenswürdige Signatur!
gpg:          Es gibt keinen Hinweis, daß die Signatur wirklich dem vorgeblichen Besitzer gehört.
      AD485664E901B867051AB15F35A2F86E29B700A4

And at least I look for the correct size of the ISO:

stephan@linux64:~/soundKonverter> sha256sum -c Leap-16.0-offline-installer-x86_64-Build171.1.install.iso.sha256
Leap-16.0-offline-installer-x86_64-Build171.1.install.iso: OK

You did not explain what you were downloading, what checksums you expected (and where they come from), how you compute these checksums (I have no idea what “right clicking on mint xfce” is supposed to mean). This does not leave much to even start guessing.

vico · November 26, 2025, 4:00pm

Sorry for being gone with lack of info

What I mean by “right clicking”:

Verify brings this menu:

It let me se the result sum (the “somaSHA256”) and also compare with files in ULRs, local files or just plain copy and paste the sum.

Regardless it never gets a good result.

You do not read my post…

vico · November 26, 2025, 5:17pm

I’m trying right now what you commented ok :]
My download was happening as you say that

I going to try the tumbleweed offline image

vico · November 26, 2025, 5:25pm

By the way @Sauerland can you explaine what “importing the project signing key” means?

Sauerland · November 26, 2025, 5:34pm

Every package in a Repo (in this special its a Repo with ISOs) is signed by a special key, so that evrybody can see, who has signed the package.

But to proof that, you have to download and activise the signature, because this can not be done automatically.

So you have to download and import this key to gpg.

After this you can proof the signature of a package by using the public key of the Repo.

Its a little bit tricky for me, english is not my native langauge and no, not using KI
Read the link of the wiki under the post

vico · November 26, 2025, 5:34pm

I not know exacly sure what disk means but I’m just keeping the file on my downloads folder on computer file sisteam
I wasn’t (but now going to try) verifying the sum on terminal, instead I was using a GUI that was already had

vico · November 26, 2025, 6:19pm

Ah finely a successful download
Maybe the GUI I was using wasn’t very good but by following the heal it was successful
