Try to change the server to main server
Open System settings > Software & Updates > Ubuntu Software > make sure you have all the source selected (main, universe, restricted, and multiverse) and select download from Main server.
Now try again sudo apt-get update && sudo apt-get install curl
Normaly, it is sudo apt-get update && sudo apt-get install curl
at 16.04.
It should work @xenial, if not, you have the wrong sources installed.
