Problem encountered on https://dotnet.microsoft.com/learn/ml-dotnet/get-started-tutorial/train Operating System: Linux Ubuntu 19.04 - x64

So, after following the tutorial. When I get to actually training this model (or just run mlnet with no arguments) I just get a message

It was not possible to find any compatible framework version The specified framework 'Microsoft.NETCore.App', version '2.1.0' was not found.

  • No frameworks were found.

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

The .NET Core frameworks can be found at:

However, if I run dotnet --info

It clearly has a bunch of these NETCore.App installed.

Do you happen to have the DOTNET_ROOT variable set to something other than /usr/share/dotnet? If it is, can you either remove the env var, or ensure it is pointing to /usr/share/dotnet?
