“Unable to locate package git” when running GitLab CI/CD pipeline

问题

I am trying to set up a GitLab CI/CD pipeline with this following .gitlab-ci.yml file:

stages:
  - test

image: "ros:foxy-ros-base-focal"

before_script:
  - apt-get -y update && apt-get install -y \
    git wget qt5-default \
    python3-osrf-pycommon \
    python3-catkin-tools \
    python3-rosdep \
    python3-vcstool \
    python3-pip \
    python3-colcon-common-extensions \
    apt-utils
  - rm -rf /var/lib/apt/lists/*
  - /bin/bash -c "source /opt/ros/${ROS_DISTRO}/setup.bash; colcon build"
  - echo "source /root/dev_ws/install/setup.bash" >> /opt/ros/${ROS_DISTRO}/setup.bash

test_a:
  stage: test
  script:
    - pip3 install pytest
    - python -m pytest test_utils.py -vv -s

I am starting from the ROS2 Foxy Base Focal Docker image. However, despite running apt-get update, I still can't find many of the packages, including git as well as several other ROS2 packages. Full log here:

Installing packages or even running update commands in your .gitlab-ci.yml is generally against best practices for a CI/CD container because each and every job that runs will have to do the same thing, costing a lot of time as you run more pipelines. If you can't find an existing Docker image that has the packages you need (so as an example, python3 and git), you can create your own images. If you need to extend the image from your job, ros:foxy-ros-base-focal, create a Dockerfile file with the following contents:

FROM ros:foxy-ros-base-focal
MAINTAINER your name "your email"
RUN apt-get update -yqq
RUN apt-get install -yqq git

You can install/configure whatever else you need to do in there too, then when you're done build the image:

docker build /path/to/dir-with-dockerfile -t tagname:version

Once the build is done you can verify the tag is correct with docker images, then you can push it to a registry (docker hub, gitlab's registry if enabled, private registry, etc) with:

docker login my.hub.example.com

docker push my.hub.example.com/tagname:version

Then in your .gitlab-ci.yml file, you can use the tagname:version image in your jobs:

stages:
  - test

image: "tagname:version"
...

If you have to auth to use your registry, you'll have to review the docs here https://docs.gitlab.com/ee/ci/docker/using_docker_images.html#define-an-image-from-a-private-container-registry, and the general docs for using docker images in your pipelines is here: https://docs.gitlab.com/ee/ci/docker/using_docker_images.html
