Hello @HELEN TRAN ,

Welcome to Microsoft Q&A forum.

Please open Visual Studio > Tools > NuGet Package Manager > Package Manager Settings > Package Sources > check if any invalid package sources are still list there, if so try to remove them or uncheck them, and make sure that the valid package source like nuget.org is checked, then retry installing NuGet package.

Besides, you may need to try to clean NuGet cache, see this document for details: Clearing local folders.

Best Regards,
Tianyu

I have a fresh install of VS 2022, with the only package source listed being nuget.org and I get this error when trying to install Microsoft.SemanticKernel.

Hi @Ray, J.D. (LCB),

Please make sure that the package source(nuget.org) has been set to https://api.nuget.org/v3/index.json. See following screenshot:

Also, please make sure that you have cleaned NuGet packages cache. Make sure that you didn’t set any global settings for package source/NuGet for example setting in the nuget.config file.

As a workaround, you can download the Microsoft.SemanticKernel package manually from here: Microsoft.SemanticKernel. After downloading, you will get a .nupkg file, in VS, click Tools > NuGet Package Manager > Package Manager Settings > Package Sources > add a new package source to that folder which contains the downloaded .nupkg file and then you can select this local package source to install Microsoft.SemanticKernel package.

Thanks. My NuGet installation, before this, had only the default configuration, which you identified. I had already downloaded the GitHub repo, so added a NuGet package source per your directions. When I select that source, it says "No packages found", and my search, either globally or specifically targeting that source, turns up nothing. Also, using the PM console throws the error Unable to find package 'microsoft.semantickernel'.

Hi @Ray, J.D. (LCB),

Thanks for your reply.

Please let us know if you have checked the Include prerelease option, as Microsoft.SemanticKernel is prerelease(beta/preview) version currently.

Also, by using PM console, did you use the complete package name of Microsoft.SemanticKernel in command line? For example: Install-Package Microsoft.SemanticKernel -Version 1.0.0-beta5.
