Docker 容器与 ubuntu 16.04 add-apt-repository 使用 groovy 而不是 xenial

Question

在我的 docker 容器中添加 ppa 存储库时遇到问题。 我在容器中的 ubuntu 版本是 16.04 ，应该是xenial ，但是当我使用add-apt-repository添加一个 ppa 存储库时，它使用的是groovy 。 问题是， groovy版本上还没有比特币 ppa 存储库。 如何解决这个问题？

这是我的 Dockerfile

FROM ubuntu:16.04
FROM node:12.18.1

RUN apt update && apt dist-upgrade -y
RUN apt install software-properties-common -y
RUN add-apt-repository ppa:bitcoin/bitcoin
RUN apt update

这是错误 output：

问题出在您的Dockerfile中：

FROM ubuntu:16.04
FROM node:12.18.1

第二个FROM命令覆盖第一个。

我似乎找不到基于 Xenial 的 Node.js 图像。 您可以尝试以下方法之一：

1. 使用node:12.18.1作为您的基础镜像，但使用基于 Debian 之类的可能满足您的要求的镜像。
2. 使用ubuntu:16.04作为您的基本映像，并在其中安装 Node.js使用类似的东西：

    curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - sudo apt-get install -y nodejs
