Question

我正在构建我的第一个dockerfile，需要安装一些软件包。目前，我正在使用Fedora，我想做的第一件事是运行dnf update && upgrade，但出现错误。

Dockerfile：

# Base image
FROM fedora:28
LABEL description="Intellij community edition 2018"

# Update and Upgrade
RUN dnf update && upgrade -y

错误：

Error: Failed to synchronize cache for repo 'updates'
The command '/bin/sh -c dnf update && upgrade -y' returned a non-zero code: 1

我已经尝试使用dnf和yum，并且还使用ubuntu作为基本映像，因此我可以尝试使用apt-get，但是我一直收到不同但相似的错误：

Err:1 http://archive.ubuntu.com/ubuntu bionic InRelease
  Temporary failure resolving 'archive.ubuntu.com'
Err:2 http://security.ubuntu.com/ubuntu bionic-security InRelease
  Temporary failure resolving 'security.ubuntu.com'

/bin/sh: 1: upgrade: not found

我已经尝试了解决这些问题的方法，但是都没有起作用：

How to install multiple packages using apt-get via a Dockerfile

运行此命令的唯一方法是使用-net = host参数从空容器中手动构建。

是否甚至可以直接从docker文件安装，更新或升级软件包，如果可以，怎么办？

在完成另一个项目不久之后，我又回到了学习docker的领域。我仍然不确定是什么导致了错误。但是在构建dockerfile时，我已经使用了不同的名称和标签，因为我已经删除了图像/容器列表。我只能认为这是与某种保留字的冲突。
