I am trying to intall the package cpprest2.10 (or cpprest), which I know is available from the repository. I know this because I have checked on https://help.ubuntu.com/

I have tried these commands:

a) sudo apt-get install cpprest2.10
b) sudo apt-get install -f
c) sudo apt-get install --fix-missing cpprest2.10

Each time I get the following messages:
