Cannot connect to a private nuget server (Azure DevOps)

I have tried to run dotnet outdated but it does not work on my computer. I have dotnet SDK 5.0.100 and the latest version of the tool 3.1.0. I also have the latest version of Microsoft.NuGet.CredentialProvider

Errors occurred while analyzing dependencies for some of your projects. Are you sure you can connect to all your configured NuGet servers? Unable to find DOTNET_HOST_PATH environment variable. If you use credential providers for your NuGet sources you need to have this set to the path to the dotnet executable.

I can set manually DOTNET_HOST_PATH but it still cannot connect to my private nuget source server :

$Env:DOTNET_HOST_PATH = "$env:ProgramFiles\dotnet\dotnet.exe"

Nuget server was added with the dotnet nuget add source command (with username and PAT token as password). The dotnet command dotnet list package --outdated works well.

The problem still occurs in Azure Pipelines. I have also tried, as suggested by @PartTimeLegend to add the Nuget Authenticate step before this but I keep getting the following error for my private feeds in Azure Devops:

Unable to find DOTNET_HOST_PATH environment variable. If you use credential providers for your NuGet sources you need to have this set to the path to the `dotnet` executable.

Any suggestions on how to fix this?

On my private vsts agent, dotnet executable is located under /usr/bin/dotnet So you may be able to hard set the env variable, that should fix it.

variables :
  DOTNET_HOST_PATH: '/usr/bin/dotnet'

The workaround i found was to:

• create a user with read-only access to the nuget feed.
• create an access token (with the longest possible ttl)
• create a nuget.config in your repo leveraging the access token like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <!-- add this line to override previously accumulated sources (e.g. from nuget.config(s) in parent directories)-->
    <clear />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
    <!-- reference to your nuget feed -->
    <add key="MyFeed" value="https://path-to-feed.com/index.json" />
  </packageSources>
  <packageSourceCredentials>
    <!-- credentials to our nuget feed -->
    <MyFeed>
      <!-- username required for authentication type. can be arbitrary but not empty -->
      <add key="Username" value="user" />
      <!-- password is PAT for the created user -->
      <add key="ClearTextPassword" value="ecampleAccesToken123" />
      <add key="ValidAuthenticationTypes" value="basic" />
    </MyFeed>
  </packageSourceCredentials>
</configuration>

This way the credentials provider is never needed. Sure it’s not the best possible solution but it works for now.
