I am experiencing this problem for the first time with Ubuntu 16.04, after a fresh installation.
Skype cannot be located after enabling Canonical Partners both in Software & Update, or by command line with the command:
sudo add-apt-repository "deb http://archive.canonical.com/ $(lsb_release -sc) partner"
Then running the following:
sudo apt-get update sudo apt-get install skype
However, I still get:
E: Unable to locate package skype
I run "sudo apt-get update --fix-missing" before trying to install skype, and this is the output I get:

I try "sudo apt-get install skype" again, and I obtain:
