This is a funny one, I’m just writing this from roughly memory.

You run “sudo apt-get update && sudo apt-get upgrade”

Ubuntu tells you that it needs to download say 25Mb and after that operation it will be using around 240kb in disk space, eh?

I have seen that quite often, but tonight I saw this one. Ubuntu needs to download around 48Mb of archives and after that it will use 244Mb more disk space, wow!

This just don’t make sense.
