我想安装yq并编辑 Docker 容器上的一些 yaml 文件。

我该如何修复它?
长话短说
该映像的 Linux 发行版yq上不提供PPA 。
更改您的 Dockerfile 以直接下载二进制文件:python:3
FROM python:3
RUN apt-get update
RUN apt-get install -y wget
# Latest on https://launchpad.net/~rmescandon/+archive/ubuntu/yq is 4.9.6
ARG VERSION=v4.9.6
ARG BINARY=yq_linux_386
RUN wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY} -O /usr/bin/yq \
&& chmod +x /usr/bin/yq

解释
上述安装说明yq需要基于 Ubuntu 的映像,但python:3Docker 映像基于 Debian 10 / Buster(截至撰写本答案时):
Dockerfile python:3= python:3.9=python:3.9.6:
FROM buildpack-deps:buster

FROM python:3
RUN apt-get update
RUN apt-get install -y wget
# Latest on https://launchpad.net/~rmescandon/+archive/ubuntu/yq is 4.9.6
ARG VERSION=v4.9.6
ARG BINARY=yq_linux_386
RUN wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY} -O /usr/bin/yq \
&& chmod +x /usr/bin/yq

错误
E:存储库“http://ppa.launchpad.net/rmescandon/yq/ubuntu impish Release”没有发布文件。
意味着该软件包ppa:rmescandon/yq 不支持您的发行版。您可以从http://ppa.launchpad.net/rmescandon/yq/ubuntu检查支持的发行版:
解决方法是从源代码安装它或仅下载yq二进制文件本身。这是由 yq 支持的: https: //github.com/mikefarah/yq#wget:
获取
使用 wget 下载预编译的二进制文件:
通过 tar.gz 压缩
Run Code Online (Sandbox Code Playgroud)wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY}.tar.gz -O - | tar xz && mv ${BINARY} /usr/bin/yq纯二进制
Run Code Online (Sandbox Code Playgroud)wget https://github.com/mikefarah/yq/releases/download/${VERSION}/${BINARY} -O /usr/bin/yq && chmod +x /usr/bin/yq例如,VERSION=v4.2.0 和 BINARY=yq_linux_amd64
从yq 的版本页面中选择一个特定版本(最好与 PPA 中为 Ubuntu 分发的版本之一匹配)并将 Dockerfile 修改为:
