Error message when uploading my sketch to a prototyping board!

Hello all, I managed to built a temperature sensor circuit using a DHT011 and it worked well while using the Arduino. However when I soldered it remotely on the prototyping board with all necessary components and connections, the sketch fails to upload and displays the error message below. Kindly help.

It is not at all clear what you mean by "prototyping board".

If you have created a PCB with an Atmega 328 on it then the first step should be to see if you can get a simple BLINK program working.

How is your PC connected to the Atmega 328?

If you need more help then you need to post a schematic of your board so we can know what exactly you are trying to do. There are dozens, if not hundreds of things that can go wrong.
