My internet connection was lost while I was updating my OS from 16.04 to 17.04 and the process stopped.There were 10-15 files remaining to be downloaded.
Now after realising that 17.04 is not a LTS version I don't wanna update my OS. But what about the downloaded files? Will they occupy any space in hard drive? Will they affect my current OS 16.04? Should I delete them? If yes than how can I find them and delete them?
