他说我缺了.NET6的环境，那就去验证下是不是真缺了。切换到路径：cd /usr/share/dotnet/shared/Microsoft.NETCore.App，`ll``一看，嘿 还真缺了：
那就只能按照它的提示老老实实去下载安装了。

上方的报错提供了一个下载地址，不知道为什么我这边无法直接访问这个地址，网上查了一下在aka前边加上www.就可以访问了，可真神奇。【官网下载地址】https://dotnet.microsoft.com/en-us/download/dotnet/thank-you/sdk-6.0.201-linux-x64-binaries。直接下载x64的Binaries

下载完之后将压缩包的这两个文件夹解压出来，通过WinSCP软件将这俩文件夹里那个6.0.3上传到服务器的对应位置去

运行成功，问题解决~
