Build caffe gpu Handshake fail DOCKER

[Özlem Akgül]

Hi,

I'd like to build a caffe image on docker for gpu, however when I type the command 

docker build -t caffe:gpu Downloads/DAN-master/docker/standalone/gpu

in command prompt on Ubuntu 20.04, it downloads some of the files while giving the error

: Failed to fetch https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/Packages  gnutls_handshake() failed: Handshake failed

W: Failed to fetch https://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1404/x86_64/Packages  gnutls_handshake() failed: Handshake failed

E: Some index files failed to download. They have been ignored, or old ones used instead.

I thought it might be due to the version of Ubuntu, or maybe that link doesn't work anymore. But when I copy the link and paste it on Google, it automatically downloads the file. Imanaged to build the cpu image but for the gpu... :(( I am totally new to Caffe and Ubuntu, and I'd be grateful if you could help. Thanks a lot! :)  Also I share my nvidia driver properties below.
