我尝试更新我的操作系统，删除未使用的软件包，使用新的操作系统来创建 docker 映像，但它总是返回此错误。有什么我错过的吗？像一些必需的依赖项或一些不兼容的软件包版本？谢谢
【问题讨论】：
-
您正在尝试在 Dockerfile 中进行大规模操作系统升级；
libc6包是一个非常底层的系统组件。你可以启动你的 DockerfileFROM一个更新的 Python 或 Debian 基础，它已经有你需要的版本吗？ -
@DavidMaze 我尝试使用
FROM python:3.9.7-slim-buster as base，但仍然遇到此错误。我不太确定我需要的 libc6 包是否在这个版本中，它是python docker hub 站点上较新的包之一。我确实尝试过'FROM 3.10.0rc2-slim-buster as base'，但我相信我的语法有错误，我得到 repository does not exist -
@DavidMaze 我发现我很粗心，在我的 3.10 版本中忽略了
python:。使用最新版本FROM python:3.10.0rc2-slim-buster as base后，我能够解决这个问题。谢谢
