I have a requirements.txt (which I got from pipreqs) that looks like this:
fastapi==0.95.2
numpy==1.24.3
pandas==2.0.1
pandas_datareader==0.10.0
pandas_market_calendars==4.1.4
protobuf==4.23.1
pydantic==1.10.7
scikit_learn==1.2.2
scipy==1.10.1
SQLAlchemy==2.0.14
toml==0.10.2
tornado==6.2
uvicorn==0.22.0
xmlrpclib==1.0.1
yfinance==0.2.18
The container file looks like this:
FROM python:3.10.9
WORKDIR /app
COPY . /app
RUN pip install --no-cache-dir -r requirements.txt
EXPOSE 3000
CMD ["uvicorn", "myapp_endpoints:app", "--host", "0.0.0.0", "--port", "3000"]
When I try to build the dockerfile:
(base) idf@R430:~/Documents/python/$ sudo docker build -t my-fastapi-app .

It doesn't matter how many lines I remove from the requirements.txt file. The next line gives a similar error.
If I restart the docker service, same problem:
sudo service docker restart
if I run it works fine
pip install -r requirements.txt
My internet connection is fine:

EDIT 1
If I run
docker run hello-world
I get:
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
Share images, automate workflows, and more with a free Docker ID:

EDIT 2
I added to the Dockerfile:
RUN curl -I https://www.google.com
I get this error:
ERROR: failed to solve: process "/bin/sh -c curl -I https://www.google.com" did not complete successfully: exit code: 6
EDIT 3
Bizarre, I tried this on another Ubuntu computer and it works. I am now confused but at least I got something
EDIT 4

I got it to work by uninstalling docker completely by following ChatGPT instructions to delete it, then followed the ChatGPT instructions to install it. LOL!
