OpenSUSE Install :: Checking The ISO File's Checksum Before Burning?
Apr 12, 2010
I downloaded the DVD ISO version of OpenSuSe version 11.2 64bit from openSUSE. I checked the iso file checksum after downloading and it was correct. However after burning to DVD i booted from the disc and started the install. After getting passed the initial settings and it starts to extract all of the packages each file fails the checksum and will not install. I tried downloading again on a different computer and burning again using UltraISO using the Disc-At-Once method, again checking the ISO file's checksum before burning.
It still gives the same errors. So i loaded windows and started the windows based install and my anti-virus (Kaspersky) says the disc is infected with a trojan. How can the disc be infected when the ISO file's checksum is correct?. The computer that i am using to burn the disc is virus free according to Kaspersky and Norton Technician Toolkit.
I am a bit unsure of checking the iso download before burning to DVD.
'Checksums
Before you burn your CD/DVD images, you should check the files for errors. Two files named *.iso.md5 and *.iso.sha1 are available. These files contains hashes for each ISO image that is available from that download location. The relevant line would look like the following:
8abac6680ecc152f103006b02f9ff67f some.iso
To be sure that download did not contain any errors, you should create this number using MS5 or SHA1 algorithm for your own ISO image.
[edit] Using Linux On Linux, run one of the command,: md5sum some.iso sha1sum some.iso
If there is any difference between the output of the checksum command and the above number, the download is broken and should be repeated.'
Is some a linux command?
I assume it is run at the same location as the download?
If you have a contiguous partial piece of an ext4 file system (assuming it's perfectly clean), starting from the beginning of the partition, is there any way to check it, or to mount it to get the files whose parents, inodes and data are all completely contained inside?
Have (or maybe had) a very large 11TB RAID 6 array, filled with a single large ext4 partition. Something strange happened when a single drive failed and the array ended up failing 13 out of the 11 drives. I had trouble getting the array restarted, and got to the point where I exhausted all of the options I considered completely safe. I considered a few things that may have worked, but mdadm doesn't seem to have a definite "do not change anything" option. So I decided the only way to be absolutely safe would be to clone the disks before proceeding - then I realized how much time that would take and sent the drives off to a recovery service so they could image them and check it out.
Before doing so, I copied the first 2GB from each disk. I XORd the images from the working drives to reconstruct the data chunks that were on the failed disk, manually assembled the chunks, and am very confident that I have 22GB of "correct" data in a single file. The parity and Q syndromes all matched (with RAID 6 you can still check with only 1 missing device). I've learned the fine details of ext4 from [URL], and have looked at lots of raw data from the reconstructed partition, and it all looks good. The recovery company says that they're not finding many inodes, but I found a lot of them, exactly where they're supposed to be. I tried to mount and e2fsk, but both processes seem to be extremely unhappy that the device size doesn't match the size implied by the file system geometry.
I considered hacking the superblock to manually reduce the size, but I figure that wouldn't work because there would then be more group descriptor blocks than it would expect after the superblocks. I might try doing that and compensating by incrementing the "reserve block count" to compensate. Alternatively, if there is some way to make the file appear to be the expected size with nothing but zeroes after the end of the actual data, maybe I could mount it and not get any errors until I cause the kernel to read past the true end of the file.
I am trying to install True Combat: Elite on my Fedora 14 machine, but when I try to install it, it tells me there is an error in the md5 checksum of the binary installer. Output:
[alex@sofy01 Desktop]$ sudo linux32 ./true.combat.elite_0.49-english.run Verifying archive integrity...Error in MD5 checksums: 3723510cf281bc315a9009cd1ca4f0e4 is different from 7cd28449f1231ff747e08fb76d4615c3
This file was copied from a flash drive onto my hard drive. Is there any way to skip md5 checks because I really do not want to download this 200+ MB file again.
I am attempting to do a new install of OpenSUSE 11.2 x86-64 by burning a network install disk. I am having trouble getting it to work on my hardware however. Whenever I boot up with the disc, I get a "image checksum error." I have tried to redownload the image and also reburn it. The disc will boot in VirtualBox but will not boot on the machine. I do not understand what could be causing this because the CD drive in the machine is working just fine.
i've decided that i wanna learn a bit of linux, and so i tried to install suse... i've come to have a lot of problems:i downloaded both the KDE Live CD and the DVD (4++ gb), both 64 bit.i dunno about the software there, but should i get the 32 bit version becouse is more likely they works or the 64 bit is fine?
what i'd like to do is overwrite my windows 7 (basically get rid of it, only way for me to use linux).i tried installing from Live CD (burned) but it does not seems to work, tried the USB thing but still something is wrong, is like is not recognized... i can't burn 4++ gb so i was wondering if there is a way to use the ISO w/o burning it... ofc i tried but in the boot menu it asks for a CD so nothing to do.
I'm trying to install OpenSuse 11.2 from iso image without burning it in a DVD.. because I don't have a CD or DVD drive.I'm using Windows Vista.firstly I mounted the dvd image .. but thought that was wrong because when rebooting instillation won't find the image.. is that true?so, I extracted it and I opened openSUSE11_2_ LOCAL.exe. and then reboot.. got two choices (Vista or install OpenSuse) and selected install OpenSuse but my screen went "out of range" !!
I've been trying to burn Suse 11.2 to a DVD now for a couple of days but I keep running into trouble. When verifying a disk after burning Suse on it it keeps giving me errors. I've tried Nero and ImgBurn, different burners, different ISOs, different burning speeds (downloaded via torrent and http) but it keeps giving me the verification error.
The only thing I haven't tried is a different brand of DVDs but until now I've never had any problems with this brand.
I have openSUSE 11.4 and added repro for Thumbleweed to the basic repro's.As told me I had to do a zypper dup ones for the Thumbleweed-repro to bring system up to date.
1) In KDE I do not see an update-icon in the system-tray anymore: 11.3 had one.Does this mean the auto-update function is disabled?
2) About "levels' of repro's: they are all 99, should Thumbleweed in my case be more important: say 75 ( at least <99 ) ?
3) When I use zypper up I have apps that wants updates and some are "hold back" Is this related to repro's that do refresh but not install ?
4) Someone told me NEVER mesh around with zypper DUP, so he means ONLY use zypper UP.
This is probably not the best question i posted on a forum, but i want to make sure i got something right on the live-upgrade page (SDB:System upgrade - openSUSE)
It says: "Check if [URL] (replace 11.3 with your version)"
I have currently 11.3 installed and want to move to 11.4. Now when it says "replace 11.3 with your version" does that mean current or version that i am migrating to?
Worst thing is i have done this before (from 11.2 to 11.3, but am not sure how i interpreted it at that time)
I have installed suse 11.2. Sometimes while using (firefox, okular, open office etc) x server restarts & comes to login screen. While checking Xorg.0.log i found i810 module is failed to load. Is this causing the x server restart?
I have several CentOS 5.5 machines running on my network; yum works just fine for them. I used the 5.5 cds to install them. I decided to grab the DVD of 5.6 and build a new machine. Can't run yum.
http://mirrors.finalasp.com/CentOS/5.6/updates/x86_64/repodata/primary.sqlite.bz2: [Errno -1] Metadata file does not match checksum Trying other mirror.
I have a problem. When I start Yast, and it tries to download the update repository, there is a checksum error. The problem is, that this error is always there, it occured about 2 weeks ago and never disappeared. When I change the update repository to a specific one, I chose a german one, there is still that checksum error. If I say yast I want to still use the repository with the error, there comes another checksum error, if i say i dont care about that one either, it says
Code: "Download failed:./repodata/primary.xml.gz could not be retrieved from http://download.opensuse.org/update/11.2/Progress:-[DownloadCommand.cc:195] caught EOF from server"
I have problem witch installing larger packages. Small packages works always. Some bigger works after few tries (like vlc-data). Large packages never works (wesnoth-1.8-music 138MB). I checked many mirrors: main, every from Poland and most from Germany. It same on kubuntu 10.10 and 11.04. My ISP doesn't use proxy of any kind. What could be the reason?
when adding the www2.ati.com/suse/11.2 repo to yast and installing the fglrxg01 I get this errormessage: Fehler: INVALIDaket ati-fglrxG01-kmp-desktop-8.593_2.6.31.5_0.1-21.1 wurde anscheinend w�hrend des Transfers besch�digt. Wollen Sie es erneut abrufen? checksum incorrect)
Suse asks me to install it anyway but then decides to not let me install it, only leaves skip, cancel and retry. when doing skip, suse also managed to fcuk up Grub and removes all the entries for suse. Installing the driver doing like ATI Proprietary Driver Install Guide | openSuSE 11.2 vanilla - openSUSE Forums
fails miserably too. the free radeon driver on my FirePro V7750 on the Dell 6400 still has artefact all over screen, I hardly can type., this linux installing is still quite frustrating. or should I try Linux maybe in a year again?
I just installed jessie on a machine that had been running wheezy with no problems. Now I see that a kworker process is hogging nearly 100% of one of the CPUs. I am not sure how to proceed with solving the problem even after doing a number of Google searches.
I'm not sure if this is related, but I am getting the following when I run 'dmesg':

I run Debian 7.9, kernel 2.6.32-5-686. I have wodim, k3b and brasero installed on my system. I have a file called sound.wav on disk, which I want to burn onto a CD so it can be played on any regular music CD player. Brasero and k3b won't let me do that - I get error messages and the CD does not get written. I used to do it with cdrecord years ago, but as you probably know cdrecord is pretty much out of the game these days; I have wodim installed instead. but I don't know how to do it with wodim.
I am using Fedora12 for about three months. I generally do a yum update once a week, and all went well till yesterday when I got a long list of messages like this:
"rpmfusion-free-updates/primary_db | 473 kB 00:00 http://mirrors.tummy.com/mirrors/rpm...ry.sqlite.bz2: [Errno -1] Metadata file does not match checksum Trying other mirror."
The above message was repeated for all the mirrors until at last it said "no more mirrors to try" and stopped. Tried again after "yum clean all", but the same problem repeats. Today I tried afresh, and got the same message.
Is this due to some recent update I did, or is there a real problem with the mirrors? Please tell me how to solve this.
After adding rpmforge on a fresh installation of CentOS 5.4 64bit, I received the error "Metadata file does not match checksum" so decided to try the fix yum -y remove yum-fastestmirror, As discussed at [URL]... Unfortunately, this also deinstalled yum. If I try to reinstall from my CentOS 5.4 DVD, I get:
# rpm -i --aid yum-3.2.22-20.el5.centos.noarch.rpm error: Failed dependencies: yum-fastestmirror is needed by yum-3.2.22-20.el5.centos.noarch
But if I try to install the yum-fastestmirror I get
# rpm -i --aid yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpm error: Failed dependencies: yum >= 3.0 is needed by yum-fastestmirror-1.1.16-13.el5.centos.noarch
I want to do is this: choose the order (other than alphabetical) of the files that I burn to a disc.Brasero doesn't allow it K3b doesn't allow it GnomeBaker doesn't allow it Unless I am missing something, I can't figure out any way other than renaming all my files with a single number and/or letter at the beginning of a file name to choose the order of files. This blows my mind it seems like the most "no duh" feature that everyone would need in any Cd burning program. if I am stupid or if the software developers are stupid. (because I really can't see any other options) This is seriously so important (to me), that I will abandon Linux and go back to Windows if I can't do it.
I was trying to burn a dvd to an image file today, and the first one worked no problem, I tried to burn another and I keep getting this error: Data could not be written (Input/output error) Here's my log:
I don't think there is a way of doing this with date or clock commands. But maybe they are writing to some file and I can take a look at the file's modification time. dmesg and /var/log/messages show nothing relevant.
