Did the problem occur during installation?

• Yes

What happened?

Installation proceeded as expected until last screen. Then, clicking to finish doesn't do anything and no crash or any other sort of output information is displayed.

What was expected?

Installation window close and the shell displays.

Steps to reproduce

Make sure Ubuntu-Preview is not registered.

1. Install the latest UbuntuPreview side load package from GitHub
2. From a terminal or command prompt execute the installation in GUI mode (ubuntu-preview.exe --ui=gui)
3. Follow the installation until the end.
4. Try to click on "Finish" button on the last screen (or any method to close the window).
5. Window will never close.

Additional information

Tested with latest UbuntuPreview from GitHub.
Subiquity logs show the installation completed successfully. No stderr or stdout from the server.
Killing the GUI process from Linux side allows the installation to complete and the shell is presented with the recently created user.
Client log shows that clicking on the Finish button attempts to submit shutdown requests to Subiquity. The server is already finished, but no exception is raised on the GUI side.

Even though we cannot see at this point, exceptions are thrown in the GUI side due lack of connection to the server, due obvious reasons.
