Hi all,

I am new to DIGITS and CUDA, and currently struggling with installation 
I am following this link for istallation on Ubuntu 14.04, CUDA- 7.5

When i do  sudo dpkg -i $CUDA_REPO_PKG (#for Access to CUDA packages) 
I get the following error message: gpg: no valid OPENPGP data found. Failed to add GPGKEY at http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/7fa2af80.pub to apt keys

My gpg --version gives "gpg (GnuPG) 1.4.16

I havnt found any solution to this problem yet, so any help will be useful! 
The instructions for #access to Machine Learning packages does not give any error messages 

Thank you!

We are aware of the problem and are working on a fix.

Sorry for the inconvenience!

You should still be able to install the packages, but you may need to ignore some missing signatures.

Thank you for your quick response!

I want to avoid using sudo apt-get --allow-unauthenticated upgrade to ignore missing signatures, as it can compromise my system.
Is there another way?

Thank you!!

I would, too. As I said, we're working on it.

Hi sir,
I am getting the same error when trying to install Cuda tool kit 7.7 from deb network package. I'm following the below link for installing DIGITS

https://github.com/NVIDIA/DIGITS/blob/master/docs/InstallCuda.md#driver

emsg@emsg:~/Downloads$ sudo dpkg -i cuda-repo-ubuntu1404_7.5-18_amd64.deb

Failed to add GPGKEY at http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/7fa2af80.pub to apt keys.

Is this problem not yet resolved, or am I doing anything wrong during installation. Please help me in this installation, I'm struggling from last one week.

I believe all the issues have been resolved. You may need to download a new version of the cuda repo package, like this one:
http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_8.0.44-1_amd64.deb
(you'll still be able to install multiple CUDA toolkits - not just 8.0)

Hi, 

'you'll still be able to install multiple CUDA toolkits' -- Could you please elaborate on that as i have CUDA 7.5

Thank you

Don't pay much attention to the CUDA version in the repo package. All the repo packages do the same thing - they give you access to all the CUDA toolkit packages. The only difference between the 7.5 repo package and the 8.0 repo package is which key it installs. The 8.0 package installs the correct key.

Hi,

I went ahead and tried setting the package mentioned above 
"sudo dkpg -i cuda-repo-ubuntu1404_8.0.44-1_amd64.deb" shows

Selecting previously unselected package cuda-repo-ubuntu1404.

Ive been struggling for over a  month now with DIGITS installation. Is there any way to debug this? ANy additional detail about my system that will help 

Thank you for your prompt replies

That's very strange. I just ran these commands in a clean Docker image and everything worked fine:

apt-get update
apt-get install wget --no-install-recommends
wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_8.0.44-1_amd64.deb
dpkg -i cuda-repo-ubuntu1404_8.0.44-1_amd64.deb
apt-get update
apt-cache policy cuda

You may want to give up on getting your local system configured properly and use nvidia-docker instead:
