dotnet CLI (dotnet new)

Describe The Bug

Installed an update to templates from a local nuget (downloaded from azure). When I tried to create an app, from the template, that generic error was reported.

DOTNET_CLI_CONTEXT_VERBOSE=true dotnet new unoapp -o unoapp                                                                                                   70 ✘  10:54:16 

Additional context

After reading on #5972 I had a look at my ~/.templateengine/packages.json and noticed duplicates. I removed the dupe and then it worked like expected.

Now it does not explain why it happened, but it means the solution for #5972 (to show something more helpful) is not working in this case.
