I am experiencing exactly the same errors inside my Docker container, behind corporate Proxy. no matter which package I am trying to install.
I could nail it down to the following:
I am getting this error as soon as any proxy env var is set (either https_proxy or HTTPS_PROXY). The curious thing it doesn´t matter if this is the right proxy or not. Also, I experienced, that when one of these vars is set, pip seems to ignore what I pass via the --proxy switch during installation.
I got it working using the following workaround:
making sure that there is neither https_proxy (lowercase), not HTTPS_PROXY (uppercase) environment var is set.
run pip install using the following command
pip3 --proxy=http://<proxyHost>:<proxyPort> install py2neo
While this workaround works for me, I would still be interested to find a resolution for this, as
I am really curious about what´s going there
it is kind of annoying to have to specify the proxy in the command inside of the Dockerfile

I think it is related with network connection in my Ubuntu subsystem. I try on Standalone Linux system and it seems to be work. How i can solve this issue?
i finnaly resolve my issue. I post below steps to solve this problem.
I checked my fireewall settings. It was not an issue.
i dont use proxy so i skipped the proxy issue.
i checked ping from the console window
ping google.com
it displayed
ping: google.com: Temporary failure in name resolution
I found a solution. Seems like my DNS server can't find an address associated to the URL i am passing. I got errors because the resolv.conf file was not set up in my Ubuntu Subsystem.
solution:
in wsl Ubuntu Linux type commamnd
sudo nano /etc/resolv.conf
add nameserver and save file
nameserver 8.8.8.8

This type of Error occurs while updating the pip.
But can be resolved by using following commands.
step 1:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
step 2:
python3 get-pip.p --force-reinstall
step 3:
Now check the pip version:
pip3 --version
This can happen with older versions of pip. Try to upgrade it with pip install --upgrade pip
I tried to pip install using proxy, the proxy setting is correct because it works for npm install . what i tried is as below shown but got error message. any idea will be more than welcome!

set https_proxy=https://<username>:<password>#<proxy_server>:<port>

pip install packageName --proxy proxy_Server:portnumber
ex: pip install numpy --proxy https://myproxy#myserver.com:9090
From https://stackoverflow.com/a/33611028/2653663 it looks like it should be
set https_proxy=<domain><username>:<password>#<proxy_server>:<port>
So port instead of ip.
set http_proxy=... and set https_proxy=.... should be enough if the proxy works.
Please run the following command to make sure that it works:
curl https://google.com

You can try downloading Django unofficial binaries form https://www.lfd.uci.edu/~gohlke/pythonlibs/ (use ctrl + F to find the package)
and install using
pip install "path to downloaded wheel file"
Edit: Offline installation of Django worked with the OP as he did not like to install the unofficial binaries.
Downloaded pytz from https://pypi.org/project/pytz/#files
And then downloaded Django from https://pypi.org/project/Django/#files
Installed wheel files of pytz first and Django next using pip.
This is because your internet proxy is blocking it. So download the installable(.whl,tz) from the server and copy to your local and install it with
pip install <downloaded file name>
