Nuget Package Source is not prompting for credentials

Question

I've added a NuGet Source. It needs credentials but when I'm installing a package using install-package packageName nothing happens. I tried the same steps on other PC and it works. I'm using Visual Studio 2017 Professional. Could someone please help me with the issue? My NuGet sources

Answer 1

If Visual Studio does not prompt for credentials but the logging Output shows that you did not authenticate correctly, then go to

Control Panel\User Accounts\Credential Manager

and click "Windows Credentials". You can remove stored credentials for nuget/github there. If they become invalid - for example because you regenerated a token - Visual Studio does not prompt to overwrite the invalid credentials, but after removing the credentials and restarting Visual Studio you do get the prompt.

I've documented more troubleshooting related to the NuGet.Config in this issue: https://github.com/verybadcat/CSharpMath/issues/168

Answer 2

This is riddiculous that it does not prompt for credentials.

To make it work I had to do the following:

1. Download nuget.exe from Nuget download site

2. Remove my old package source

   Go to NuGet Package Manager for Solution->Settings

Delete your Package Source

3. Run Command Line

   Go to nuget.exe

4. Add package source with plain password in the command

   nuget.exe sources Add -Name "YourPackageName" -Source "YourPackageAddress" -Username YourUserName -password YourPassword -StorePasswordInClearText

5. Done... phew

Answer 3

After many attempts to set password, reset password or whatever the only thing that helped me was adding this section to the NuGet.Config (located on the .nuget folder for the main solution)

NuGet.Config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <solution>
    <add key="disableSourceControlIntegration" value="false" />
  </solution>
  <packageSourceCredentials>
    <MySourceName> <!-- Name of nuget package source -->
      <add key="Username" value="..." />
      <add key="ClearTextPassword" value="..." /> <!-- This is for normal password-->
      <!--if encrypted use key="Password"-->
    </MySourceName>
  </packageSourceCredentials>
</configuration>

One important notice - for any change to this file to take effect I had to restart VS

Answer 4

Remove the source from the Nuget Package Manager and add it with a new name.
