Apt update failing on Ubuntu CUDA repo

Accelerated Computing CUDA CUDA Setup and Installation

When I run apt update on Ubuntu 18.04, I am getting

This is on a PC that used to update correctly. I also tried installing CUDA on a fresh Ubuntu 18.04 install and got the same result. Is the CUDA repo broken?

#2

This seems to have been resolved. Perhaps the repos were being updated. (Maybe adding Ubuntu 20.04, support?)

#3

the problem remains on multiple dockers…
see: https://github.com/PyTorchLightning/pytorch-lightning/pull/3821

#4

Same/similar problem again, breaks automated builds. Looks like the package repository at https://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64/ is broken. Packages.gz was updated on 2020-09-23, but the hash files were not updated to match, causing apt-get update to fail.

@w01 did you find a way to fix this?

From previous similar posts, the most common resolution seems to be to wait and hope someone from nvidia notices and fixes it, I don’t know if there is a way to report problems like this to them directly.

An easy way to reproduce this problem is using their container images, for any CUDA version:

docker run -it --rm nvidia/cudagl:11.0-devel-ubuntu18.04 bash
# Inside the container:
apt-get update

Checking today, 2020-10-19, this appears to have been fixed again. The example with a container image above now works.

…and apparently broken again a short time later:

docker run -it --rm nvidia/cudagl:11.0-devel-ubuntu18.04 bash
# Inside the container:
apt-get update

Hi all, I’m experiencing the same issue. It was working correctly for me until an hour ago and then broke.

Any fix for this? It’s breaking my builds and I can’t solve it. I would really appreciate your help

Seems broken to me (Ubuntu 20.04). This is the line in /etc/apt/sources.list.d/nvidia-machine-learning.list

deb http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1804/x86_64 /

Then, sudo apt update gives the error
