Bad checksum for Cuda 8.0 for Ubuntu 14.04

I was having the problem yesterday on Ubuntu 14.04 but it is now working for me this morning. I am using the deb network package that downloads the updates from Nvidia.

Closing the loop on this.

We believe that all of the corrupted file issues have been resolved, so please let us know if you experience any further problems installing any version of CUDA 8.

Thanks,

Will.

Hi all and Will. I am new here and still facing the same issue.

I don’t know whether it’s because of my download managers or what, But I’m getting different md5sums each time I download them and none of them matches to the server’s md5sum.

Currently I’ve 6 copies of the cuda_8.0.61_375.26_linux.run. Two of them by clicking on the 16.04 version under Ubuntu, two by clicking on the 14.04 version, one from the link provided by Nico00 and one using wget instead of download managers. All the md5sums are as follows:

462ef980483110814fd4ab449588a214
7f48ab18859aac1c1e9f8bcf72d619ae
7f48ab18859aac1c1e9f8bcf72d619ae
f16b92bc57b30a2288d2ef4ed42dca66
0496bead7c30152cc9c91a54aeb4e566
0496bead7c30152cc9c91a54aeb4e566

The 2nd and 3rd and 5th and 6th are matching. So I think if all of them are corrupted while downloading, it’s a rare chance for 2nd and 3rd or 5th and 6th to get corrupt at exact same point and give same md5sum.

For all 6 copies above, I’m getting a error:

gzip: stdin: invalid compressed data--format violated
Extraction failed.
Ensure there is enough space in /tmp and that the installation package is not corrupt
Signal caught, cleaning up

Can anyone tell me how to solve this, or provide a link of the correct file?

P.S. There’s no success from the *.deb local file also.
Before someone asks, My location is India.

Wget-ing Nico00’s link finally worked. I had to do the Wget in a remote machine where Internet is quite good. Then ftp from there to my machine. Then only I got the correct md5sum.

For anyone who’s getting this error, use the below link with wget and match the md5sum.

You might get other errors later, for which there are resources available. But make sure that you get the correct file, not a corrupt one.

Hi Ratdon,
I am sorry that you have been experiencing problems downloading our installers. The file you were downloading is over 1.3G as such you may have been experiencing extended download times.

I would be interested to know more about the download managers you were using and the time it took to download this file when you were experiencing problems.

When you were not using Nico00’s link - what links were you using? There is only one valid link for this file - so I am curious about the alternatives - which I believe are temp links which would expire during your download experiments - hence resulting in consistent partial downloads - hence repeated md5.

I also confirm the correct md5 is as you stated: 33e1bd980e91af4e55f3ef835c103f9b.

I will be happy to help and provide guidance on best ways to download these files.

Thanks for responding.

Yeah seems like there’s only one link. I never checked the actual link as my download manager was showing a temporary link along with the original.

I’ve used wget, Downthemall (firefox plugin), XDM, IDM. None of them worked. I’ve a shitty Internet connection which varies from 2 KBps to 600 KBps. Download time took 1+ hours to 6-7 hours (many times failing and unable to resume and had to restart from begining). Once I tried with XDM and Downthemall with 5-6 MBps also. There also I got wrong checksum. May be it was because download managers were trying to download segment by segment.

With a constant 600 MBps connection, with wget, I succeeded to download and get the correct checksum. Though it took more than 2 hours to ftp the file from that remote system to my machine, but there was no server restrictions this time.

But I’m surprised that all other files are working fine after downloaded by download managers. What is the problem with this file only? or there are any serious server restrictions which shouldn’t have been there?

Now everything is working fine and am off to use hashcat with CUDA. Thanks again.

Hello,
I downloaded cuda-repo-ubuntu1404_8.0.61-1_amd64.deb today.

When I ran the checksum it threw an error. Obtained checksum from:
http://developer2.download.nvidia.com/compute/cuda/8.0/secure/Prod2/docs/sidebar/md5sum.txt?IaLHslDfs09GwrEuQDiNwbvlaQX_y2pdmLdBjWG_4qVFh4CjBvfYFIPJiusiyl1f5GHKVsAIpnjNf3uvwVO8dfu2ocerOiH_azoQhy6DqY4G1Q5FfN-iyL84e5cBXgcGoQnCNtlgbqPx4-BsYQPvFOMNUfo

Here is the command I used
‘cf41f620dcebccd7a669d8ef3f31aeac cuda-repo-ubuntu1404_8.0.61-1_amd64.deb’ | md5sum -c

Output:
“cf41f620dcebccd7a669d8ef3f31aeac cuda-repo-ubuntu1404_8.0.61-1_amd64.deb: command not found
md5sum: standard input: no properly formatted MD5 checksum lines found”

A little concerned about this so I did not proceed with my install. Is there something wrong?

Thanks.

Hi tf1015,

The “command not found” error is because the .deb file is not a command that can be executed.
And the error message from md5sum in the second line of the output above is because no file was specified as a parameter for md5sum to process.

Try running this instead:
md5sum cuda-repo-ubuntu1404_8.0.61-1_amd64.deb

And you should get a checksum value followed by the filename as the output, which you can then confirm matches the checksum value you expect.

Ok now I’m having the same problem as everyone else on this thread. Downloading CUDA 9 for Ubuntu 16.04 on a fresh install, get

gzip: stdin: unexpected end of file
Extraction failed.

And the checksum fails:

matt@matt-Precision-Tower-7810:~/Downloads$ md5sum cuda_9.0.176_384.81_linux.run
3bf9bbd0754dd9014d884868447944ae cuda_9.0.176_384.81_linux.run

versus

7a00187b2ce5c5e350e68882f42dd507 cuda_9.0.176_384.81_linux.run

frome here: http://developer.download.nvidia.com/compute/cuda/9.0/Prod/docs/sidebar/md5sum.txt

WTF? How can this not be fixed? More importantly How can I make it work?

@electrofizz, the “gzip: stdin: unexpected end of file” error message suggests that the file did not download completely.

Please try downloading the file again, and if you get the same error message & incorrect checksum, please share the size of the file you downloaded as well as the error message(s).

Thanks,

Will.
