无法在 Ubuntu Bionic Beaver 上安装 .NET Core

  • 772

我目前正在尝试按照这些说明在 Ubuntu 18.04 上安装 .NET Core。但我总是收到以下消息：

me@mine-Ubuntu:~$ sudo apt-get install -y dotnet-sdk-2.1.200
[sudo] password for me: 
Reading package lists... Done
Building dependency tree       
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:
 dotnet-sdk-2.1.200 : Depends: dotnet-runtime-2.0.7 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我发现了一些关于这个问题的帖子，但没有帮助。我希望在这里得到一些适当的信息。

  1. 首先添加来源：

    wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/ubuntu/18.04/prod.list 
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list

    在那之后：

    sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-2.1.200

    sudo apt-get update很重要

    安装后libicu55，您需要安装其他不会自行安装的包依赖项：

    sudo apt-get install dotnet-runtime-deps-2.2
sudo apt-get install dotnet-runtime-2.2
sudo apt-get install aspnetcore-runtime-2.2

    然后sudo apt=get install dotnet-sdk-2.x

  3. 注册 Microsoft 密钥和提要

    在安装 .NET 之前，您需要注册 Microsoft 密钥、注册产品存储库并安装所需的依赖项。每台机器只需执行一次。

    打开终端并运行以下命令：

    wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/ubuntu/18.04/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

    安装 .NET SDK

    更新可供安装的产品，然后安装 .NET SDK。

    在您的终端中，运行以下命令：

    sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-2.1

  4. 你需要安装libicu55：

    sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt-get update
sudo apt-get install libicu55

    然后安装网络核心：

    sudo apt-get install dotnet-sdk-2.1
