I had the same problem but was able to solve it by installing dotnet from https://dotnet.microsoft.com/en-us/download/dotnet/8.0 instead of from homebrew.

I am encountering a similar issue with the Upgrade Assistant (version 0.5.711) on a Mac M1 machine. When attempting to use the tool, I receive the following error:

I have tried reinstalling the tool and ensuring that all necessary environment variables are correctly set. However, the issue persists.

Steps to Reproduce:

1. Install Upgrade Assistant version 0.5.711.
2. Run upgrade-assistant command.
3. Observe the error message.

Any assistance or guidance on resolving this issue would be greatly appreciated.

Thank you!

[jstedfast]

Can you try installing the dotnet 8.0 runtime/sdk? I've always run this using dotnet 8.0

[jstedfast]

Sorry, just noticed you have net8.0 installed

[jstedfast]

I just made sure to install the exact same versions of the SDK/runtimes and updated my upgrade-assistant as well and am unable to reproduce this issue :(

[sergey-fuflygin]

Thanks for the quick response!

I’ve verified that .NET 8.0 SDK and runtime are installed, as you suggested. Additionally, I’ve tried uninstalling and reinstalling various versions of the Upgrade Assistant.

Since the issue persists, could there be any other underlying factors or configurations that might be impacting the Upgrade Assistant? Any additional guidance or troubleshooting steps you could provide would be greatly appreciated.

@jstedfast in my case, the issue was related to MSBuildLocator and was fixed by adding /usr/local/share/dotnet to the PATH environment variable as suggested here.

Thanks for your support!

Good to know, thanks for sharing!
