Get the following error message when trying to build the docker compose.

Package 'docker-ce-cli' has no installation candidate

Screenshot of the Lab Page 2 and the Error Output are attached with this message.

I guess the package docker-ce-cli isn’t there in the image?

    @Shivinder I'll look into it.

    @ericegan I guess I’ve figured out the issue. The package docker-ce-cli isn’t available for the arm64 arch. I tried to execute the steps inside the docker image manually and after I reached the step where I need to install the docker-ce-cli package, it failed, as expected.
    I listed the packages, and figured out the arch is different. I am on arm64. But the docker image is a amd64, do you think it should still work?

    Or maybe the Dockerfile line which adds the repository to the image, needs to be ammended,

    RUN add-apt-repository \
           "deb [arch=amd64] https://download.docker.com/linux/debian \
           $(lsb_release -cs) stable”

    It clearly says arch=amd64 in there.

    I modied the Dockerfile and used the correct arch for my laptop here, the issue did not happen.
    I have attached the terminal output from the run with arch set to amd64 with this ticket.

    The output from the terminal where I set the arch to arm64 is below:

    root@cf3526be43ee:/# add-apt-repository "deb [arch=arm64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
    root@cf3526be43ee:/# apt-get update && apt-get install -y docker-ce-cli

    So I guess this works for me for now.

    Hi @Shivinder , I have seen more than one issue when working with arm based systems (in more than just this course). So you may expect some trouble, perhaps in performance and other stuff.
