Question

Ubuntu 20.04出现问题。我遵循official instruction并安装了SDK和运行时。如果可以从终端确认：

dotnet --list-sdks
3.1.403 [/usr/share/dotnet/sdk]

和运行时：

dotnet --list-runtimes
Microsoft.AspNetCore.App 3.1.9 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 3.1.9 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

...但是我正在尝试的项目dotnet run需要Microsoft.AspNetCore.App 2.2.8，如从日志中可以看到的那样：

It was not possible to find any compatible framework version
The framework 'Microsoft.AspNetCore.App', version '2.2.8' was not found.
  - The following frameworks were found:
      3.1.9 at [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:
  - https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=2.2.8&arch=x64&rid=ubuntu.20.04-x64

安装缺少的SDK和运行时的正确方法是什么？

Answer 1

因此，上述运行时不支持Ubuntu 20.04，因此必须手动安装它们。在我的特定情况下，to download binaries就足够了，并像往常一样运行它们。

全新安装后在`Ubuntu 20.04`上缺少版本'2.2.8`的`Microsoft.AspNetCore.App`
