Bad checksum for Cuda 8.0 for Ubuntu 14.04


As we investigate further, it’s looking like the problem may be in the CDN replication process.

So it’s possible that files that are working fine in some geographies are corrupted in the local cache for other geographies.

Apologies again for the inconvenience, and thanks for you continued patience as we work with the CDN vendor to triage the problem and get a fix in place.


I try to download the CUDA Toolkit 8.0 GA1 from CUDA Toolkit Archive, however it doesn’t work when install. Sorry.

bad Hash problem.
unable to install cuda 8.0 on ubuntu 14.04.5
GTX 1060 asus.
just buyed new card for my project.

I’m investigating the same issues with, even so successfully loaded it on 9/02. Current checksum is 416979dd6df6fe601d99facd0cfe2874.

Any chance you could give us a link to a non-corrupted version on your own servers, or just stick it on DropBox or something, temporarily? :)


Same issue with Ubuntu 16.04 kernel 4.4.0-62-generic.

md5: 416979dd6df6fe601d99facd0cfe2874



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

Downloaded from UK via Nvidia website

Guess I should try 7 , hope its ok with the current tensorFlow.

Good hunting Nvidia.



Thank you, Will, that seems to have done the trick for me. The version of served in the US gives me the proper md5sum 6dca912f9b7e2b7569b0074a41713640.

If I proxy through to the USA, it doesn’t even offer version 8.0.61_375.26! Nice to know people can get the older version if they need it, though.

else would be nice to support fedora 24 and 25 ;) 23 seems eol now, no more updates

Thanks Epsylon3, but that doesn’t contain
only the .deb files. Having already installed the graphics drivers via a .run file, I now have to do the same with the CUDA drivers or it won’t work :-/

i just made it on 14.04, you can upgrade cuda without the drivers with these deb files. they are placed in /usr/local/cuda-8.0 like the .run

dpkg -i cuda-nvml-dev-8-0_8.0.61-1_amd64.deb cuda-license-8-0_8.0.61-1_amd64.deb
dpkg -i cuda-command-line-tools-8-0_8.0.61-1_amd64.deb cuda-cudart-dev-8-0_8.0.61-1_amd64.deb cuda-driver-dev-8-0_8.0.61-1_amd64.deb cuda-cudart-8-0_8.0.61-1_amd64.deb   cuda-core-8-0_8.0.61-1_amd64.deb cuda-misc-headers-8-0_8.0.61-1_amd64.deb

didnt install visual stuff, i dont run X on it… also note i didnt use apt

It seems that fixing this problem requires more time than expected and that NVIDIA for the moment have restored the previous version 8.0.44 everywhere.

This is how I’ve downloaded the working file for Ubuntu 16.04:

The downloaded file has the correct MD5 (33e1bd980e91af4e55f3ef835c103f9b) and actually works without any error message.

THANK YOU Nico00, I didn’t have the direct link. That’s downloading now (and will take hours on my very rural broadband) so I’ll let you know when I’ve got it.

Thanks again,

i confirm i was able to get this md5 from a montreal server

I just downloaded the .run file for Ubuntu 16.04 and successfully installed CUDA 8.0 with it. Thanks for fixing this.

Thanks everyone, I’ve now managed to download this with the correct checksum, and it runs. Won’t install, of course, but I’ll start a new thread about that!

Hey guys just updating you on my case, i successfully downloaded cuda 8.0.61-1 for ubuntu 14.04 using the .deb (network) method and executing

#apt-get install cuda --fix-missing

just now 20:18 U.S central time

Quick update:

We’ve root-caused the problem and a fix is in progress.

Everything should be back to normal by tomorrow morning Pacific time.

Apologies again for the inconvenience.
