Package 'qt5-default' has no installation candidate

[MariaHei]

Hi,

I'm trying to build a container on Mac OS Catalina 10.15.4 but run into the following error:

import SimpleContainerGenerator

mkpath("my_image_name")
cd("my_image_name")

pkgs = [
           "DataFrames"
       ]

julia_version = v"1.4.0"

SimpleContainerGenerator.create_dockerfile(pkgs;
                                                  julia_version = julia_version,
                                                  output_directory = pwd())

run(`docker build -t my_user_name/my_image_name .`)

Do you have any idea what I could do to fix this?

+1 on this I get the same error.

This seems to be an issue with the ubuntu:latest base image being used. Past Ubuntu 21, the qt5-default package no longer exists.

While we wait for the maintainers to fix the issue, there are two workarounds that I've managed to get working:

1. Explicitly set the base image to ubuntu:20.04 in the generated Dockerfile:

FROM ubuntu:20.04  # <-- change the very first line
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update

You can also set this in on the create_dockerfile function with the parent_image argument

2. Replace qt5-default with the packages that are explicitly installed during the apt-get install step:

# I've replaced qt5-default with qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools
