package checksum mismatch installing 11.1 64bit

English Install/Boot/Login
#1

trying to install opensuse 11.1 64bit shows for multiple packages the following message:

Wrong Digest

The expected checksum of file /var/cache/zypp/packages/openSUSE 11.1-0/suse/i586/wv-1.2.2-177.97.i586.rpm is … but the current checksum is …

This means that the file has been changed by accident or by an attacker since the repository creator signed it. Using it is a big risk for the integrity and security of your system.

Use it anyway?

this message is shown for ~30 packages.

is this problem known? how do i proceed?

Sounds like you have a bad DVD, if you are using a DVD.

#3

indeed, but i downloaded it from opensuse.org, and the md5checksum seemed to be ok.

#4

If your checksum matches with the checksum on the download site, then you have exactly the same ISO.

  • hemathor,

sounds like a broken installation media. When you boot from the CD/DVD, there’s an option to check or verify the media. Try that, I expect it to throw errors.

Did you burn the media from a downloaded ISO? If that’s the case, verify the download’s MD5 sum. If it isn’t correct, download it again. If it is correct, burn the media at a very low speed.

Yeah, but that’s the ISO file on disk. You should also check it after the burn in case you have a dodgy blank. Did you run the media check on bootup from the DVD?

that’s it! checksum was wrong. strange…

Did you burn the media from a downloaded ISO? If that’s the case, verify the download’s MD5 sum. If it isn’t correct, download it again. If it is correct, burn the media at a very low speed.

i ran the installation directly from the iso-image.

downloading the image again, and try once more…

thanks a lot for the help! :slight_smile:

There are several points at which it is a good idea to check.

  1. Md5sum the ISO download. Why? Because it may have been corrupted in transit. While bittorrent is claimed to reduce chance of corruption, do take the time to compute the sum, it will only take less than a minute and save much pain later.

  2. Verify after the burn. Why? You might have a faulty CD/DVD or drive.

  3. Verify by running the media check. Why? This seems redundant to number 2. But if you are installing on a different machine, then note that you are using a different drive!

If you are installing directly from the ISO image via NFS, SMB or local file, then there’s no number 2, but 3 is still a good idea. You don’t need to redo 1 if you have a good md5sum for the ISO image file.

I got a similar error when using a “well used” dvd-rw disc.

I had this problem also, with a broken ISO downloaded from openSUSE site:
It complains also about keys or what its called that cant be found. (GPG keys, this signed keys or what they call them)

But it worked to install anyway for me and the system works fine.
I just disabled the “Deploying Image” thing and added the main repo and non-oss repo and the installation worked fine.

It seems that i dont have to re-download over 4 GB again :wink:

I’ve had problems with the 64 bit version of the install too. It installed 6 or 7 times (Courtesy of AsusTek and one of their dodgy Mobos) and then started throwing errors. I put the DVD in a cleaner and it works OK again. Guess it was just a dust-bug.

I am having the same trouble. I deleted all the keys and repositories and readded the update repository. It’s working a little better, but it stil pops up a lot of errors.
