在 ubuntu 中安装 .net core 2.0 sdk 时出错

我尝试在 ubuntu 17.04 中安装 .net core 2.0，但出现如下错误

**Reading package lists... Done

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:
 dotnet-sdk-2.0.0 : Depends: dotnet-runtime-2.0.0 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.**

正在使用下面的过程来安装它

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-zesty-prod zesty main" > /etc/apt/sources.list.d/dotnetdev.list' 
sudo apt-get update

sudo apt-get install dotnet-sdk-2.0.0

请帮我修复这个问题。

SDK 版本和链接取决于你的 ubuntu 版本，你必须在列表。但如果你使用 18.04，你必须遵循这些命令

# NO_PUBKEY EB3E94ADBE1229CF
sudo apt-key adv --keyserver packages.microsoft.com --recv-keys EB3E94ADBE1229CF

# NO_PUBKEY B02C46DF417A0893
sudo apt-key adv --keyserver packages.microsoft.com --recv-keys 52E16F86FEE04B979B07E28DB02C46DF417A0893

sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-bionic-prod bionic main" > /etc/apt/sources.list.d/dotnetdev.list'

sudo apt update
sudo apt install dotnet-sdk-2.1.300-preview2-008533

我遇到了同样的问题，结果发现我没有使用 17.04。我在 Windows 10 上的 WSL 中，它的版本实际上是 14.04。我检查了版本：

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.5 LTS
Release:        14.04
Codename:       trusty

所以...正确的安装命令是：

sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-trusty-prod trusty main" > /etc/apt/sources.list.d/dotnetdev.list' 
sudo apt-get update
sudo apt-get install dotnet-sdk-2.0.0
