我正在尝试按照本教程在 PC/jetson nano-ARM64（运行 ubuntu 18.04）上构建/运行 Android Cuttlefish：如何在 PC/ARM64 上构建/运行 Cuttlefish
在某个时候，我应该这样做：
[在 ARM64 上]
设置运行 x86_64 二进制文件
以 root 用户身份执行以下操作：
apt install qemu-user-static
dpkg --add-architecture amd64
删除 ubuntu 源并在 /etc/apt/source.list 上添加这些源：
deb [arch=arm64,armhf]http://ports.ubuntu.com/ubuntu-ports/仿生主受限宇宙多元宇宙
deb-src [arch=arm64,armhf]http://ports.ubuntu.com/ubuntu-ports/ 仿生主受限宇宙多元宇宙

apt update
apt install libc6:amd64
这种方法的后果是 ubuntu 删除了系统上已安装的所有 arm64 软件包，系统彻底崩溃。我该如何避免这种情况？
更新 1：有人告诉我：“dpkg 的多架构工作方式的一个棘手之处在于，要为多个架构安装库，所有架构的软件包版本必须完全相同。因此，如果由于某种原因，当前安装在您系统上的 libc6:arm64 软件包的版本与您要求其安装的 libc6:amd64 软件包的版本不完全相同，apt 可能会建议通过删除 libc6:arm64 来解决这个问题。而且由于几乎所有东西都依赖于 libc，因此必须删除大量软件包。要确定这是否真的是问题的原因，您应该找出这两个架构可用/安装了哪些版本的 libc6。重要的不是源代码的高级版本，而是二进制软件包的确切版本。例如，如果您有用于 arm64 的 libc6 版本 2.27-3ubuntu1，但有用于 amd64 的 libc6 版本 2.27-3ubuntu1.2，那么你不能同时安装两者。即使它们都来自同一个上游源”
我已经确定升级后 ubuntu 18.04 使用：
libc6_2.27-3ubuntu1.4_arm64.deb；libc-bin (2.27-3ubuntu1.4)。
我已经下载但未使用以下命令安装 libc6:amd64：
apt-get download libc6:amd64
我看到它的版本是：libc6_2.27-3ubuntu1.2_amd64.deb....
更新 2：此命令序列不起作用：
gedit sources.list
apt update
apt install qemu-user-static
dpkg --add-architecture amd64
apd update
apt install libc6:amd64
