Failed to retrieve information about 'Telerik.UI.for.AspNet.Core' from remote source

[Sebastian]

Hey, 

All our pipelines have broken due to the sunsetting of the V2 endpoint, my attempt at fixing these have stopped with this error

##[error]The nuget command failed with exit code(1) and error(NU1301: Failed to retrieve information about 'Telerik.UI.for.AspNet.Core' from remote source 'https://nuget.telerik.com/v3/nuget/FindPackagesById()?id='Telerik.UI.for.AspNet.Core'&semVerLevel=2.0.0'.

this is happening in an azure devops pipeline using the latest nuget version 

we are using a nuget.config file in the same folder as our .sln

and this is what the file looks like (minus the real credentials)


<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />

</packageSources>

</packageSource>
</packageSourceMapping>

</configuration>


any ideas? we would really like to deploy again...

Also, this works perfectly fine on our local machines.

Hеllo Sebastian,

Thank you for the provided information.

The issue you started to experience is due to the scheduled brownout of the Telerik NuGet v2 server - v2 NuGet - Scheduled Brownout. Starting in November 2024, the Telerik NuGet v2 server will be decommissioned, so you need to update your system to use the v3 NuGet service -  (https://nuget.telerik.com/v3/index.json).  For more information on the reasons behind this decision and how to prepare, refer to the Sunsetting the NuGet v2 Server.

Since you have already upgraded to v3 server and the issue persists,  would you please let me know how is configured the DevOps pipeline? Most probably, the v2 feed is not updated everywhere (i.e., in the NuGet.config file). For more information on how to set up the Telerik package source, refer to the Azure DevOps and Telerik NuGet Packages.

Additional Information: The Telerik NuGet v3 server has been showing no downtime in the last 90 days - Telerik Status

I hope this information helps. Let me know if I can assist you furthe.

Regards,
Maria

The same is happening in Mac (Xamarin proj). I tried adding and removing the Telerik Nuget source from VS for Mac and keychain access, still looking in 

Failed to retrieve information about 'Telerik.UI.for.Xamarin' from remote source 'https://nuget.telerik.com/nuget/FindPackagesById()?id='Telerik.UI.for.Xamarin'&semVerLevel=2.0.0'.

Any idea what to do next?

Hello,

We are aware of a few cases where customers experience issues accessing the telerik feed due to firewall restrictions. In order to check the availability of Telerik.UI.for.Xamarin nuget from Telerik remote Nuget Feed could you please paste the follwing link in your browser and get back with the result on your side? You'll need to enter your Telerik credentials into the pop-up prompt that should appear.

Here is the result on my side:

https://nuget.telerik.com/v3/package/telerik.ui.for.xamarin/index.json 

If you want to validate the successful download of certain version you could try the following link for example:

https://nuget.telerik.com/v3/package/telerik.ui.for.xamarin/2024.4.1112/telerik.ui.for.xamarin.nupkg 

It downloads  Telerik.UI.for.Xamarin.2024.4.1112.nupkg on my side.

If this doesn't work you could try once again removing the telerik nuget feed and add it again. 

Here is a help article which also contains a video showing how to configure the Telerik NuGet feed in Visual Studio:

https://docs.telerik.com/devtools/xamarin/installation-and-deployment/telerik-nuget-server 

I hope this helps.
