Hi list,



- and a HAPPY NEW YEAR TO ALL!

Same to you :-)


- I'm puzzled by md5sums. I've downloaded openSuSE11 (both 32 and 64 bit versions) and openSuSE11.1 (32/64 too).

- I get the same odd errors with 11 as with 11.1. This is my situation:

I try to verify the md5sum of openSuSE11(i386/32), it should be

ed6a5b3feb668866df812b1c2aed9d7f openSUSE-11.0-DVD-i386.iso

ed6a5b3feb668866df812b1c2aed9d7f openSUSE-11.0-DVD-i386.iso

Correct, yes.

but using "md5sum openSUSE-11.0-DVD-i386.iso", I get:

a38623810009842eeb1542a2052cfc2d openSUSE-11.0-DVD-i386.iso

This, of course, is wrong. If I do a

yep, wrong.


"md5sum -c openSUSE-11.0-DVD-i386.iso", I get 500+ lines saying the this or that -rpm file could not be read, general i/o error or so"

Actually, it should be:

md5sum -c MD5SUMS

where "MD5SUMS" is the file containing the text line above, ie, the checksums and filenames.


Now if I burn an ISO DVD, it verifies correctly when doing the "check media" before installation (!).

What!?

I would report that as a bug.

Installation starts fine, but in some cases breaks later on, but not always... I use K3B for burning, it reports a sound md5sum.

Well, it reports that it burned correctly the image you gave it, which we know is bad.

I downloaded the isos from mirrors and directly from SuSE too. I downloaded from two different locations, albeit to the same PC (my laptop). I stored the received files (during download) onto the harddisk and also onto a USB stick.

And all of them have the same (incorrect) checksum?

Same story. As you can tell, I've done quite a few downloads...All the downloaded files yield the same md5sum (using md5sum without the -c flag), never mind what media I store onto. And regardless of wherefrom and my method of downloading.

The same incorrect checksum? All of them? Wow.

By the way, check the image before burning it. If it is incorrect,
don't bother burning.


As of now, I'm not really able to install openSuSE11(1) to anything, as I can't seem to get this right.

Questions:

a)
The md5sums listed on the openSuSE web are (of course) correct

b)
what's the correct and proper way of verifying the md5sums?

md5sum -c md5sumfilename


c)
I used wget, firefox directly and a FF-extension called DownThenAll for downloading. What would be your recommendation?

aria2c (metalink link), from here:

http://download.opensuse.org/distribution/11.0/iso/dvd/

if you want the 11.0 version, or

http://download.opensuse.org/distribution/11.1/iso/

if you want the new, 11.1 version. Use the comand line program "aria2c", feeding it the "metalink" link address; for example:

aria2c --max-download-limit=85K --max-upload-limit=12K http://download.opensuse.org/distribution/11.1/iso/openSUSE-11.1-DVD-i586.iso.metalink

you will have to download aria2c first, though.


Info on "metalink":

<http://en.opensuse.org/Download_Help#Downloading_via_Metalinks>

The reason is that this method should provide a corrected iso file. More info here:

<http://lizards.opensuse.org/2008/12/16/best-way-to-download-opensuse/>


Another method, as you already have the image, with errors, is to repair it. Here you have instructions:

<http://en.opensuse.org/Download_Help#Repairing_a_Download>

Carlos E. R.

Thank You!

- so much knowledge and info, so little time :-)
- I'll get on to it right away, first I dig into aria2c. Oil keep you posted, said the sheik!

Best regards,
Verner
