NVHPC yum/dnf repo broken for ppc64le

NVHPC repository for ppc64le is missing the repodata directory, so it’s effectively broken:

[root@power ~]# dnf install nvhpc
Updating Subscription Management repositories.
NVIDIA HPC SDK                                                                                                               191  B/s | 433  B     00:02    
Errors during downloading metadata for repository 'nvhpc':
  - Status code: 404 for https://developer.download.nvidia.com/hpc-sdk/rhel/ppc64le/repodata/repomd.xml (IP: 152.199.52.179)
Error: Failed to download metadata for repo 'nvhpc': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

I tried to manually download the RPM but it also complains about missing nvhpc-24-1 package. Which is also unavailable on: Index of /hpc-sdk/rhel/ppc64le

[root@power ~]# rpm -i nvhpc-24-1-cuda-multi-24.1-1.ppc64le.rpm 
warning: nvhpc-24-1-cuda-multi-24.1-1.ppc64le.rpm: Header V4 RSA/SHA512 Signature, key ID 264a7796: NOKEY
error: Failed dependencies:
	nvhpc-24-1 = 24.1 is needed by nvhpc-24-1-cuda-multi-24.1-1.ppc64le

Thanks.

Thanks ferrao, I let our DevOps folk know about the dnf issue. We discontinued support for PowerPC as of the 24.3 release, but the repo should still be able to point to 24.1.

For the manual download method, you need two RPMs:

https://developer.download.nvidia.com/hpc-sdk/rhel/ppc64le/nvhpc-24-1-cuda-multi-24.1-1.ppc64le.rpm
https://developer.download.nvidia.com/hpc-sdk/rhel/ppc64le/nvhpc-24-1-24.1-1.ppc64le.rpm

And then run:

dnf install nvhpc-24-1-cuda-multi-24.1-1.ppc64le.rpm nvhpc-24-1-24.1-1.ppc64le.rpm

I have fixed the repodata issue.

DevOps just restored the repo, so the initial method should be working again.

Thank you @MatColgrove and @jmudd

It’s already working here:

[root@power ~]# dnf install nvhpc-cuda-multi
