installation of docker on ubuntu: unable to connect to github.com

I am using this guide to install docker on an ubuntu server; below is a list of commands that succeed:

sudo apt-get install apt-transport-https ca-certificates curl gnupg
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
apt-cache madison docker-ce
sudo apt-get install docker-ce=5:20.10.5~3-0~ubuntu-focal docker-ce-cli=5:20.10.5~3-0~ubuntu-focal containerd.io
sudo docker run hello-world

and the following command ends with an exception which I could not figure out. I am just appending the last few lines of the output, i.e. there several more lines like 'Pull complete' which for simplicity are not pasted.

$ sudo docker build . --rm -t unet_industrial:latest
...
64b042356f2f: Pull complete 
cc20fc4ac4a7: Pull complete 

  Running command git clone -q git://github.com/NVIDIA/dllogger /tmp/pip-install-qk44vpx2/dllogger_fe6a3cc31bd747099e88bb9266898680
  fatal: unable to connect to github.com:
  github.com[0: 140.82.121.3]: errno=Connection timed out

WARNING: Discarding git+git://github.com/NVIDIA/dllogger#egg=dllogger. Command errored out with exit status 128: git clone -q git://github.com/NVIDIA/dllogger /tmp/pip-install-qk44vpx2/dllogger_fe6a3cc31bd747099e88bb9266898680 Check the logs for full command output.
ERROR: Could not find a version that satisfies the requirement dllogger (unavailable)
ERROR: No matching distribution found for dllogger (unavailable)

In addition, I am posting here the Dockerfile which ought to be changed because it was ascertained that the git clone command works upon using https:// in lieu of git://

ARG FROM_IMAGE_NAME=nvcr.io/nvidia/tensorflow:20.06-tf1-py3
FROM ${FROM_IMAGE_NAME}

WORKDIR /opt
COPY requirements.txt /opt/requirements_unet_tf_industrial.txt

RUN python -m pip --no-cache-dir --no-cache install --upgrade pip && \
    pip --no-cache-dir --no-cache install -r /opt/requirements_unet_tf_industrial.txt

ENV TF_EXTRA_PTXAS_OPTIONS="-sw200428197=true"

ADD . /workspace/unet_industrial
WORKDIR /workspace/unet_industrial

I don't think it's proxy related as you're able to pull apt packages and execute curl commands. Perhaps it's related to SSH (perhaps not configured) - can you try cloning repo using HTTPS instead e.g. git clone -q https://github.com/NVIDIA/dllogger.git /tmp/pip-install-qk44vpx2/dllogger_fe6a3cc31bd747099e88bb9266898680

let me know how it goes...

This is not related to install of docker on ubuntu, but related to your projects' Dockerfile build.

From your error log, it looks there are next in your Dockerfile:

pip install git+git://github.com/NVIDIA/dllogger

When pip install from a github repo, it will first try to download the source code with:

git clone -q git://github.com/NVIDIA/dllogger

Unfortunately, when docker do build it will also start a build container, but looks your build container can't visit github.

A probable reason is you are behind a proxy, then you need add proxy when build like next:

$ docker build --build-arg http_proxy=your_http_proxy --build-arg https_proxy=your_https_proxy -t unet_industrial:latest .
