Impossible to install drivers on fresh Ubuntu focal

Ansible role fails with :

It seems that the whole by-hash dir is missing on nvidia repos :
https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/by-hash/

As a workaround I had to change the the apt_repository task on my side adding a special by-hash=no option to avoid previous error :

$ cat /etc/apt/sources.list.d/developer_download_nvidia_com_compute_cuda_repos_ubuntu2004_x86_64.list 
deb [by-hash=no] http://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64 /

Is it a transient issue on nvidia repo side ? Or should we permanently add this "no-hash" fix on ansible templates ?

Thanks

Hi, I had the same issue
the solution is there #42

You have to use

https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64 /

instead of

http://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64 /
