我正在尝试安装 .NET Core 包，但遇到问题并且不知道如何解决。
我按照此页面上的步骤操作，但收到以下错误：https://dotnet.microsoft.com/download/linux-package-manager/ubuntu18-04/sdk-2.1.202
我遵循整个指令，这是我的输出：

难道是我做错了什么？我的机器有问题吗？
答案1
这可能不是包的名称。如果您正在搜索一个包来使用该apt-cache search命令，我建议您。
像这样的东西
sudo apt-cache search dotnet
这应该根据您安装的存储库找到描述或名称中包含“dotnet”的所有软件包。
答案2
我找到了解决办法，首先使用root安装。如果您使用Unbutun 18.04，您还需要预先添加此脚本：
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
add-apt-repository universe
apt-get install apt-transport-https
apt-get update
apt-get install dotnet-sdk-2.1.202
