The weird part is it then proceeds to show my git log ...

I actually tried the GitVersion .NET Core version and it also did not work. I got the error Cannot find module 'argparse'

[Gimly]

The exact same issue happens with the MacOS hosted images.

[romain-pfund]

Same issue here on MacOS, any news ?

[AClarkie]

Any update on this?

@EwanNoble can you uninstall the extension from the organization and install it again? Looks like you have cashed the older version

[EwanNoble]

I have removed the old preview extension and installed the new one and now GitVersion is working successfully on my Linux agents. Thank you very much @arturcic !
