openSUSE 11.4 download errors

I have downloaded openSUSE 11.4 twice. Both times the Yast Check Media showed that the md5 checksums did not match.

To check further, I ran md5sum from terminal with the following result:

jch@linux-7v61:/media/9bc17414-31cf-4fb6-b676-59838e1d61f2/OpenSUSE> md5sum openSUSE*
082ebfac494b41cd56b38fb4218c545d  openSUSE-11.4-DVD-x86_64.iso
jch@linux-7v61:/media/9bc17414-31cf-4fb6-b676-59838e1d61f2/OpenSUSE> 

I downloaded using FTP from

Does anyone have any suggestions before I do another large download?

In the help page there are instructions on how to recover a bad download.
Me, I would use aria2c and metalinks.

I thought about the download recovery but decided I would probably waste more time and effort recovering a bad download than it takes to do it again. I’ll just start it when I get ready to go to bed and it will be there in the morning.

Thank you for the reply. If the FTP doesn’t work a third time, I will try something else. I have downloaded lots of software with FTP and this is the first time I ever had a problem. I was wondering if maybe the mirror site hadn’t been updated or something. I will try another on this time.

why do you ask for advice, get it (from a guy who knows what he is
talking about) and then ignore it in order to repeat an already twice
failed download?

if you decide to try something else, i’d suggest you try it the way
Carlos suggested…

hmmmm…is that the actual calculated output?

i ask, because to me that looks like the exactly correct checksum…

see here:
http://download.opensuse.org/distribution/11.4/iso/openSUSE-11.4-DVD-x86_64.iso.md5

so??

Recovering a bad download could be a question of minutes.

It is the correct checksum. That is the point of the original post, although (looking back) I did not make it clear to begin with.

Yast Media Check rejects the .iso as invalid. Which should I trust?

I did burn a CD of that file and attempted to install it on my second computer (thinking the md5sum was right and Yast was wrong). I ran into problems with the monitor/display on first boot. I could not complete configuration without a working monitor/display. (I should note that the display worked fine during installation) Only at that point did I start kicking myself for going ahead with a questionable installation DVD.

The second computer is where I try new things. The fact that is isn’t working isn’t a big deal - it often doesn’t work because I often screw it up playing with things I don’t understand (like setting up an Apache server to test and customize !Joomla locally). I have re-installed many times when it goes FUBAR.

I do not want to crash this computer because I rely on it for daily work. I won’t attempt to install here until it works letter perfect on the second computer.

I do not reject the expert advice I get here. I appreciate it very much and follow up with learning about the things suggested to me by the generous expert volunteers here. It just takes time to learn when I am busy with other things. I try not to be a pain (70 posts on a handful of topics over three years) to the experts here or abuse the privileges of forum membership.

Thank you for the reply and advice.

Thank you for the advice.

I will learn more about the recovery process and metalink downloads you suggest. It just takes time to learn about all these things.

It has to be a bug in the yast media check. I have no idea why it says it
is bad.

There is a problem when checking md5sum on the burned DVD, because the size
is rounded up to an exact sector number (or even a track), whereas the iso
file doesn’t do that. You have to tell md5sum how many bytes it has to check.

Yast media check, on the other hand, has to check itself excluding the
place where the value is stored. If you calculate a value then write it to
the iso image at the right place, the checksum varies. I don’t know how
exactly they do it, but it is tricky.

I will just fiddle with it until it works or I learn enough to ask another question.

I am retired and getting older, but computers have been a lifelong passion. For someone who grew up without electricity, the advances in my lifetime are simply amazing beyond belief. It just blows my mind to think of the possibilities and opportunity for today’s young people!

I am not a professional nor do I have any formal training. I am sure my ignorance is frustrating to people who are professionals. I should take some classes instead of plowing through 2000 page books and online tutorials on my own. At least then I could ask the right questions and speak the language.

Thank you for your patience and advice.

The correct check sum is
082ebfac494b41cd56b38fb4218c545d

Which you have.

Checking the .iso and the burned DVD are different. In that even though the .iso is correct, the burned DVD might not be.

The link you quoted in post #1 is not for a _64 .iso?!

It’s not clear to me if you are talking about working with a burned DVD or not. If you are burning a DVD you absolutely must use good media and burn slowly.

and after the disk is burned, then boot from it and do this:
http://tinyurl.com/455hbml which will check that the the disk was
correctly burned…

then install…and, if you get that “I ran into problems with the
monitor/display on first boot.” then try another boot this way:

when you see the first green screen press the down arrow (that will stop
the system so you can then type (just start typing and it will fall in
the right place)


nomodeset

then press enter and cross your fingers…if that gives you a good
screen then come back and say so…

do NOT worry about “I try not to be a pain (70 posts on a handful of
topics over three years) to the experts here or abuse the privileges of
forum membership.” because we are here to help YOU…

The checksum and Yast Media Check were on the File, not the CD. The _64 file did come from the link posted or at least I think it did.

Last night’s download came from:
http://mirrors1.kernel.org/opensuse/distribution/11.4/iso/openSUSE-11.4-DVD-x86_64.iso (us, prio 65)
The 5mdsum checks on it also. I have not had time to do the Yast Media Check on this file nor have I burned a CD yet.

I will post more later when I have time.

A DVD image will not fit on a CD

Sorry - I misspoke. It was a Maxell DVD-R, not a CD. I don’t even think I own a blank CD, I just used the term generically to mean a “disk”. I think I must be getting old.

Cordially,
TwoHoot

OK. Here is some new information.

The md5sum on the download file checks from terminal. I do not know how to check the DVD from terminal.

Yast Check Media returns an Error message BOTH on the .iso file and the DVD. The message reads (in red):

“MD5 Sum does not match
This medium should not be used”

Booting with the DVD and running the “Check Installation Media” as suggested by DenverD reports “No Errors Found”.

I will start the installation on the second computer and report what happens next.

TwoHoot

The “Check Installation Media” reports “No Errors Found”

After installation when it was booting for configuration, I pressed the down arrow key at the first green screen and typed ‘nomodeset’ as you suggested. Same result with the monitor/display - It is vertical stripes of green gibbrish like before.

But … something is different because I can get a good screen this time by booting in Failsafe mode.

Am I right in thinking that the wrong display/monitor drivers might have been installed?

Cordially,
Twohoot

I don’t believe you told us what graphics?

Fail safe includes other parameters, one or more of those may be what is allowing the boot. You can see them at boot by moving to the text area at the bottom of the screen and scrolling back and forth. They can also be seen/changed in Yast-boot configure and in /boot/grub/menu.lst file.

truth is i’ve used openSUSE exclusively since 9.2 and i’d heard of “Yast
Check Media” until i saw it in your post…

why not you go ahead and write a bug on that, here:
http://tinyurl.com/nzhq7j

it could be that that section of YaST is so old no one has looked at it
in years, and no one will until there is a bug to prompt…

It is the on-board video of the Gigabyte M61PME-S2P motherboard. I think it is NVIDIA GeForce 6100/nForce 430.

The monitor is a Samsung SyncMaster 910MP.
