Can not install dotnet-ef through CLI (Unauthorized)

[think3wang]

I am trying to install dotnet-ef package through dotnet cli, how ever it gave me 401 (Unauthorized) error.

The command I run is dotnet tool install --global dotnet-ef what I don't understand is, the dotnet-ef is a public package that anyone can install, what is this "authorized" about?

The detailed result I got is :

C:\Program Files\dotnet\sdk\3.1.300\NuGet.targets(128,5): error : Unable to load the service index for source https://microsoft.pkgs.visualstudio.com/_packaging/Universal.Store/nuget/v3/index.json. [C:\Users\<myUserName>\AppData\Local\Temp\wojjcmbm.aon\restore.csproj]

The authentication relates to the package feed it's trying to access. Check your global nuget.config file for that package source and potentially remove it. You can run dotnet nuget list source to see which sources you are using by default.

You can also try to run with --ignore-failed-sources.

I'm getting the same issue. I'm not using any custom nuget.config files. These are my listed packages. I'm getting this error with .NET 5.0.100.

dotnet nuget list source
Registered Sources:
  1.  nuget.org [Enabled]
      https://api.nuget.org/v3/index.json
  2.  Microsoft Visual Studio Offline Packages [Enabled]
      C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\

If you have many sources for packages you will need to include " --ignore-failed-sources", that worked for me. dotnet tool install --global dotnet-ef --version 5.0.13 --ignore-failed-sources

I had to add nuget.config file with the following content -

@prags9 What content? A dash?

I had some additional custom sources. Just using --ignore-failed-sources wasn't enough. I went into Visual Studio -> Tools -> Options -> NuGet Package Manager -> Package Sources and unchecked the extra package sources so only nuget.org and Microsoft Visual Studio Offline Packages was left checked. After doing that I was able to install the tool using dotnet tool install dotnet-ef --global --ignore-failed-sources, and then I re-enabled my custom package sources.

I confirm: --ignore-failed-sources, isn't working, still getting 401 (Unauthorized). I temporarely removed the additional sources from the global nuget config file, then I was able to succesfully run dotnet tool install --global dotnet-ef
