无法在UBuntu 18.04上安装.Net Core 2.2

Question

我试图将ASP.NET Core 2.2应用程序部署到运行Ubuntu 18.04的DigitalOcean droplet.我按照官方文件中提供的步骤进行操作. https://dotnet.microsoft.com/download/linux-package-manager/ubuntu18-04/sdk-current.

但是我收到了错误.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 dotnet-sdk-2.2 : Depends: aspnetcore-runtime-2.2 (>= 2.2.0) but it is not going to be installed
                  Depends: dotnet-runtime-2.2 (>= 2.2.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

有帮助吗？我试图从其他论坛获得帮助,所以答案仍然没有运气.
