I have received an old Mac Pro G5 running Mac OS X Leopard, and have tried updating it to its newest possible form. When I downloaded Mac OS X High Sierra and even Snow Leopard, it says “Can not update” when I try to open the update file (Through USB).
By the way, I was connected to the internet by ethernet.
