cudnn-8.0-linux-x64-v5.1.tgz checksum failure #7

Closed nexusdk closed 7 years ago

nexusdk commented 7 years ago

ebuild sh256 is a87cb2df2e5e7cc0a05e266734e679ee1a2fadad6f06af82a76ed81a23b102c8 File download sha256 is c10719b36f2dd6e9ddc63e3189affaa1a94d7d027e63b71c3f64d449ab0645ce

I downloaded the file twice, got the same sha256.

Hm, I checked the file on my laptop: ares archenroot # sha256sum /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz a87cb2df2e5e7cc0a05e266734e679ee1a2fadad6f06af82a76ed81a23b102c8 /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz

Additionally the output: ares archenroot # ls -la /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz -rw-rw-r-- 1 portage portage 100504805 Dec 2 21:23 /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz

Can you provide download link?

nexusdk commented 7 years ago

Here is the file I have: ftp://ftp.cs.up.ac.za/cudnn-8.0-linux-x64-v5.1.tgz

I cannot download the file. Anyway I downloaded again file from official Nvidia site at: https://developer.nvidia.com/rdp/cudnn-download

Now I checked newly downloaded file against the one I have in /usr/portage/distfiles:

ares ~ # sha256sum /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz 
a87cb2df2e5e7cc0a05e266734e679ee1a2fadad6f06af82a76ed81a23b102c8  /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz
ares ~ # ls -la /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz 
-rw-rw-r-- 1 portage portage 100504805 Dec  2 21:23 /usr/portage/distfiles/cudnn-8.0-linux-x64-v5.1.tgz

Now newly downloaded file:

zangetsu@ares ~/Downloads $ sha256sum cudnn-8.0-linux-x64-v5.1.tgz 
c10719b36f2dd6e9ddc63e3189affaa1a94d7d027e63b71c3f64d449ab0645ce  cudnn-8.0-linux-x64-v5.1.tgz
zangetsu@ares ~/Downloads $ ls -la cudnn-8.0-linux-x64-v5.1.tgz 
-rw-r--r-- 1 zangetsu users 103174002 11. May 13.54 cudnn-8.0-linux-x64-v5.1.tgz

So, either they replaced the file with some other version during time and I won't be surprised as I was able to build... or I had corrupted download file, but in that case I expect not being able to compile as some files are missing...

Anyway I replaced obsolete file with latest available from Nvidia which has same sha256sum string as yours and now it should work, I emerged with result:

Let me know if all ok now.

Regarding th QA Notice this is related to strip by upstream:

Note: Some packages unfortunately handle stripping by themselves, inside the upstream provided makefiles. This is an error and should be reported. All packages should leave Portage the task of the stripping or simply restrict stripping entirely. The main exception to this are binary packages. They are usually stripped by upstream, outside of Portage control.

Closing as fixed now.
