linux - 在 Armbian 上安装 .Net 5 Runtime 时出现错误(在 Orange Pi Zero 上)

Question

我正在尝试在 Armbian Focal (Ubuntu 20.04) 或 Buster (Debian 10) 上安装 .Net 5 运行时，在 Orange Pi Zero 上运行。
所以我在这里按照微软的指示:
https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu
但在最后一步:

sudo apt-get install -y aspnetcore-runtime-5.0

我收到此错误:

E: Unable to locate package aspnetcore-runtime-5.0
E: Couldn't find any package by glob 'aspnetcore-runtime-5.0'
E: Couldn't find any package by regex 'aspnetcore-runtime-5.0'

然后我按照微软的建议从这里手动安装它:
https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#apt-troubleshooting
但在最后一步，我又得到了同样的错误。
有任何想法吗？
总之，这些是我首先尝试的步骤:

wget https://packages.microsoft.com/config/ubuntu/20.10/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update; \
  sudo apt-get install -y apt-transport-https && \
  sudo apt-get update && \
  sudo apt-get install -y aspnetcore-runtime-5.0

这些是我在上述失败时尝试的步骤:

sudo dpkg --purge packages-microsoft-prod && sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install -y gpg
wget -O - https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor -o microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget https://packages.microsoft.com/config/ubuntu/{os-version}/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list
sudo apt-get update; \
  sudo apt-get install -y apt-transport-https && \
  sudo apt-get update && \
  sudo apt-get install -y aspnetcore-runtime-5.0

编辑:
我之前在完全相同的设置上安装了 .Net Core 3.1 运行时，没有任何问题。我不确定 .Net 5 中是否有一些不同的东西不允许我安装它

从您链接的第一个 URL:https://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu

Package manager installs are only supported on the x64 architecture. Other architectures, such as ARM, must install .NET by some other means such as with Snap, an installer script, or through a manual binary installation.

Pi 是 ARM 设备，因此不支持您尝试使用的安装方法。
