添加arm64多重弓对Ubuntu18.04图像产生误差

Question

以下是如何重现这一问题：

docker run -it ubuntu:18.04 bash

apt-get update
dpkg --add-architecture arm64
apt-get update

最后一个apt-get update的输出是许多未发现错误的行：

为什么会发生这种事？我该如何解决这些问题？我希望这个能拍出新的画面.

编辑另一件奇怪的事情如下。在我自己的机器上，如果我运行sudo apt-get install libopenblas-dev:arm64，就会得到libopenblas-dev:arm64 is already the newest version，这意味着可以找到这个包。

但是，在docker映像中运行命令apt-get install libopenblas-dev:arm64返回：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libopenblas-dev:arm64

不知道为什么在我的机器上找到这个包(也运行Ubuntu18.04)，但是在图像中找不到。

Answer 1

这些存储库只包含i386和amd64体系结构。在：dists/focal/目录中为自己检查( http://archive.ubuntu.com/ubuntu目录)

添加arm64存储库，这些存储库位于http://ports.ubuntu.com/ubuntu-ports/中
