install problem

[178yun]

I use these codes to install dipasm:

mkdir -p dipasm
cd dipasm
git clone https://github.com/shilpagarg/DipAsm.git
cd DipAsm/docker
docker build -t dipasm .
cd ../../..
docker run -it --rm -v $PWD/dipasm/DipAsm:/wd/dipasm/DipAsm/ -e HOSTWD=$PWD/dipasm/DipAsm -v /var/run/docker.sock:/var/run/docker.sock dipasm:latest /bin/bash

But the output:

$ docker build -t dipasm .
Sending build context to Docker daemon   7.68kB
Step 1/22 : FROM continuumio/miniconda3
Head "https://registry-1.docker.io/v2/continuumio/miniconda3/manifests/latest": Get "https://auth.docker.io/token?scope=repository%3Acontinuumio%2Fminiconda3%3Apull&service=registry.docker.io": net/http: TLS handshake timeout

$docker build -t dipasm .
Sending build context to Docker daemon   7.68kB
Step 1/22 : FROM continuumio/miniconda3
Head "https://registry-1.docker.io/v2/continuumio/miniconda3/manifests/latest": Get "https://auth.docker.io/token?scope=repository%3Acontinuumio%2Fminiconda3%3Apull&service=registry.docker.io": net/http: TLS handshake timeout

I am quite unfamilar with docker. I don't know how to solve it.
