Steps to reproduce the issue

1. Build this Dockerfile (.NET Core SDK) - https://github.com/MichaelSimons/dotnet-docker/blob/3204d3bc5e488140b63b0e2edc46953f1030cc3d/3.0/sdk/nanoserver-1809/arm32v7/Dockerfile
2. Build the following Dockerfile based on the image produced from step 1

FROM dotnet/core-nightly/sdk:3.0-nanoserver-1809-arm32v7

RUN dotnet new web --framework netcoreapp3.0 --no-restore
