无法按照glob 'dotnet-sdk-2.1' 找到任何软件包
等等

你系统是不是32位的？它只支持64位

[sunck1970]

哦，原来这样，我是32位的，非常感谢

[sunck1970]

昨天安装了一个64位的ubuntu server 18.04版本，然后安装.net 2.1仍然报错无法定位软件包
后来一个朋友提示把软件包下载下来安装，终于搞定了
下载地址是https://www.microsoft.com/net/download

下载Binaries里面的x64文件， 用u盘拷贝到服务器上，再执行下列命令终于安装成功了
mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-2.1.500-linux-x64.tar.gz -C $HOME/dotnet
export DOTNET_ROOT=$HOME/dotnet
export PATH=$PATH:$HOME/dotnet


另外 如果unbutu是桌面版本，在家里的笔记本上安装的，然后在线安装。net 2.1是没有问题，不知道服务器版本为啥出问题

应该是服务器版的universe源默认没启用吧。谁叫你不严格按照官方指引做 https://www.microsoft.com/net/download/ ... dk-current

[sunck1970]

不是什么默认没有启用，我是严格安装微软的文档操作的，是微软的在线安装不支持server版本

不可能的。它的安装方式根本没法区分是服务器版还是桌面版。我也在18.04的服务器上试过了，毫无问题
