在 Google Colab 上安装 .NET Core

Question

我正在尝试在 Google Colab 上安装 .NET Core。我按照给出的说明进行操作（适用于 Ubuntu 17.10）：

! wget -q https://packages.microsoft.com/config/ubuntu/17.10/packages-microsoft-prod.deb
! dpkg -i packages-microsoft-prod.deb
! apt-get install apt-transport-https
! apt-get update

在我尝试安装 aspnetcore-runtime-2.1 之前，这一切正常：

! apt-get install aspnetcore-runtime-2.1

并得到这个错误：

Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 aspnetcore-runtime-2.1 : Depends: dotnet-runtime-2.1 (>= 2.1.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

您可以清楚地看到缺少一个依赖项：dotnet-runtime-2.1。问题是我无法单独安装它，因此不存在依赖性问题。谁能帮我这个 ？

Google colab 目前使用的是 ubuntu 版本 18.04.3。您可以使用它来检查它，

! lsb_release -a

因此，您需要关注 Microsoft guide 以获取该版本。 按顺序依次执行这些步骤。

! wget -q https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
! dpkg -i packages-microsoft-prod.deb
! add-apt-repository universe
! apt-get update
! apt-get install apt-transport-https
! apt-get update
! apt-get install dotnet-sdk-3.1

这是一个可工作的 colab 笔记本 -> https://colab.research.google.com/drive/19ZM4sIccSOgNjX3hQW0KUFsVbZCrGXTY

您可以检查它是否安装正确，

! dotnet --list-sdks
