I don't know how to install Skype on Ubuntu 16.04.1. It was all okay until I updated my Ubuntu and now I can't install Skype.
You can get Skype 4.3 on 16.04 by enabling the Partners repository, as others have said. However, it isn't really worth it. Skype will open, but you won't be able to do a lot of things, including group calls (this is a problem with all Linux distros). You may or may not also have dependency issues, as these have been reported on 16.04.
Instead of Skype 4.3, you should get the Skype for Linux Alpha app (download the DEB). It's still in alpha, as the name suggests, but it currently has all the features of Skype Web.
If you want to fully use Skype on Ubuntu 16.04, you'll need the Alpha version.
You could use Franz. Franz is a free messaging app.
- Download it from here: Download Franz e.g. the 64bit Linux version
- Extract it:
cd /tmp; mkdir Franz; tar xvfz Franz-linux-x64-3.1.1.tgz -C Franz
- Place it:
sudo cp -a Franz /opt/Franz; sudo ln -s /opt/Franz/Franz /usr/local/bin/.
- Run it: Press
- Add Skype Service using your login and password
