Error: retrieving gpg key timed out

[joseverav]

I cloned the repository and tried to run the docker-compose --verbose build command, but I get an error. It seems that it is related to the docker/backend/Dockerfile where the ubuntu:xenial image is created. Here is the error output:

#0 17.98 gpg: keyring `/tmp/tmpmfnsuaam/secring.gpg' created

Hi @joseverav,

could you try to update the ubuntu image in the docker/backend/Dockerfile from ubuntu:xenial to ubuntu:jammy? Do you still have the error?

[joseverav]

I tried that and I am still getting the error. Do you get this error at all when using the master branch? Because I want to rule out the possibility of the error being produced by something in my local machine.

The solution that worked for me was to change images from ubuntu:xenial to ubuntu:jammy and update from Python 3.6 to 3.8. Here is what docker/backend/Dockerfile looks like now:

FROM ubuntu:jammy

ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update && \
    apt-get install -y software-properties-common && \
    add-apt-repository ppa:deadsnakes/ppa -y && \
    apt-get update && \
    apt-get install -y python3.8 python3.8-dev python3-pip python3.8-distutils

WORKDIR /app
COPY requirements.txt .
RUN rm -f /usr/bin/python && ln -s /usr/bin/python3.8 /usr/bin/python
RUN rm -f /usr/bin/python3 && ln -s /usr/bin/python3.8 /usr/bin/python3

RUN pip3 install -r requirements.txt
RUN pip3 install gunicorn==19.9.0

ADD ./backend /app/backend
ADD ./docker /app/docker
ADD ./research /app/research

#RUN mkdir -p /app/backend/server/staticfiles
RUN mkdir -p /app/backend/server/static

I also had to update scikit-learn to version 0.24.2 in requirements.txt. I can make a pull request for this @pplonski if it is helpful.

Though my docker image gets built, running docker compose up creates a new error. See my new issue.
