change this to return result.returncode == 0 this will return True if the condition meet and False otherwise. If you look at how the install function executes the installer' steps, it checks if one of them returns False

Bottles/bottles/backend/managers/installer.py

Lines 421 to 424 in 2bd8b60

if not self.__perform_steps(_config, steps):
return Result(
False, data={"message": "Installer is not well configured."}
)
and then return a proper Result object according to that.

Currently, there is no easy way to show a message to the user graphically. It could be possible by making each step returning a tuple (boolean, message) and have the install function append that message to the Result object, then updating the installer view in the frontend to use that message if available

adding the line return result.returncode == 0 results in a known failure (exit 1) in the script not even putting a warning in the Console, and just continuing with the rest of the manifest steps.

Same goes for adding
return False
or

      return Result( 
         False, data={"message": "Installer is not well configured."} 
     )

Bottles just continues on with the rest of the manifest regardless of the failure

It looks like there is something missing to handle the return at this point, as it continues regardless of any state returned

# an error happened!
err_msg = "Status: FAIL \nError: %s\nCode: %s" % (result.stderr.decode(), result.returncode)
logging.error(err_msg)
# raise Exception(err_msg) #Raise blocking error
logging.info(f"Finished executing installer script.")
