Microsoft EntityFramework Core CLI install - nuget exception

Question

I am trying to install dotnet-ef globally on macos 10.15.6 dotnet tool install -g dotnet --version 3.1.6 I am getting nuget exception

"/var/folders/gt/9l4q1djd12d__wt0cxkqyrc80000gn/T/bw0oop0h.aau/restore.csproj" (Restore target) (1) ->
                   (Restore target) -> 
                     /usr/local/share/dotnet/sdk/3.1.302/NuGet.targets(128,5): error : Object reference not set to an instance of an object. [/var/folders/gt/9l4q1djd12d__wt0cxkqyrc80000gn/T/bw0oop0h.aau/restore.csproj]

The exception is happening here:

 System.NullReferenceException: Object reference not set to an instance of an object.
                        at NuGet.Protocol.ServiceIndexResourceV3Provider.GetServiceIndexResourceV3(SourceRepository source, DateTime utcNow, ILogger log, CancellationToken token)

and here is a screenshot for the entire stack

I spent 3 days with this. I would appreciate any kind of help

Answer 1

I solved the problem after intensive SDK/Runtime uninstalling process combining dotnet uninstall tool and manual chasing and removing for folders and install everything all over again. Uninstalling tool doesn't remove cache folders which is a huge problem considering that the problem by large affected by caching in my opinion. I seached on mac on everything with dotnet nuget entityframework and removed it manually case the tool don't really remove everything. Depending on the uninstall tool alone didn't help me.
