dotnet restore and AzureDevops private feed in WSL

Question

I need to run an Asp.Net Core application in WSL (Ubuntu 22.04), I'm trying to execute command:

dotnet restore

to restore my nuget packages from default nuget.org and from my private feed on Azure Devops Server 2019. I set the feed in NuGet.config file with credentials and API key like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <add key="Nuget" value="https://api.nuget.org/v3/index.json"/>
        <add key="MyFeed" value="https://devops.myfeed.com/tfs/company/_packaging/CompanyPackages/nuget/v3/index.json"/>
    </packageSources>
    <packageSourceCredentials>
        <MyFeed>
            <add key="Username" value="DOMAIN\User"/>
            <add key="ClearTextPassword" value="PATforPackages"/>
        </MyFeed>
    </packageSourceCredentials>
</configuration>

But i always get an 401 Unauthorized error. Has anyone had the same problem? How can I solve it? Thanks

UPDATE This is the log stack trace:

UPDATE I updated the NuGet.Config file as above

UPDATE 2
The solution recommended by @wade zhou - MSFT to use this configuration

--valid-authentication-types basic

with the PAT (Personal Access Token) works perfectly. Thanks

Answer 1

But i always get an 401 Unauthorized error.

It appears you have disabled the DevOps feed myfeed in Nuget.Config. Please remove it from <disabledPackageSources> section.

In addtion, the 401 error indicates the user doesn't have permission or PAT is not correct. please follow below items to check:

1. Make sure the user has permission on the DevOps feed.

2. Generate a new PAT token with package read scope at least. Put it in the nuget.config.

Specify the Nuget.config file in the command:

$ dotnet restore <project>.csproj --configfile NuGet.config --verbosity detailed

In WSL, make sure it can access the target Azure devops server site.

The restore result on my side for your reference:
