Error installing upgrade-assistant tool

Problem encountered on https://dotnet.microsoft.com/platform/upgrade-assistant/tutorial/install-try-convert
Operating System: windows

Provide details about the problem you're experiencing. Include your operating system version, exact error message, code sample, and anything else that is relevant.

Tried following the instructions to install the upgrade-assistant (preview) tool. Similar error occurs when installing "upgrade-assistant" as when following the steps and installing "try-convert" (below). Error message is not sufficiently clear on what the issue is. Ran the following command, with error output:

PS C:\Users\uname\temp> dotnet tool install -g try-convert
C:\Program Files\dotnet\sdk\5.0.103\NuGet.targets(131,5): error : Unable to load the service index for source h

The tool package could not be restored.
Tool 'try-convert' failed to install. This failure may have been caused by:

• You are attempting to install a preview release and did not use the --version option to specify the version.
• A package by this name was found, but it was not a .NET tool.
• The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
• You mistyped the name of the tool.

@cathysull , if it helps at all, the Azure DevOps project it's referencing no longer exists (I deleted it sometime over the past month). I went looking in the named directories in my local file system. E.g. the "NuGet.targets" file has a disclaimer at the top warning me about editing it directly, so it's not really clear how to flush or otherwise detach this dependency on a "no longer existing" Azure DevOps project. And I'm not even sure what the dependency is or how it got there.

I have the same issue with try-convert not installing.

@skeeler, .NET CLI tools are installed as NuGet packages. It looks like you have NuGet configuration that is adding an authenticated NuGet feed (it lists the URL in the error message) and install is failing because it's trying to restore from that feed without credentials.

Can you aren't installing from a location subject to a NuGet.config file and that NuGet's configuration isn't listing any authenticated feeds and try again?

@mjrousos , thanks for the doc link to the NuGet config file locations. The nuget.exe command-line didn't help (i.e. nuget.exe config), but I was able to find the orphaned package reference in %appdata%\NuGet\nuget.config, remove it by editing the config file, re-ran the "dotnet tool install -g upgrade-assistant" command, and it worked!

Closing as issue is resolved with @mjrousos assistance. Thank you.

@mrjrousos, this is a common scenario, having an authenticated feed, and I don't believe changing the nuget config file is the correct solution (because you have to remember to change it back). Supposedly the issue with dotnet has been fixed in newer versions to support authenticated feeds but there is mixed results.

I think the instructions should be updated to perhaps mention authenticated feed scenarios with the recommendation to use the --ignore-failed-sources flag during installation. This will cause authenticated sources to be skipped if they fail.

[mjrousos]

Good suggestion, @CoolDadTx. I'll add that to the docs.
