Unable to Install Skype On Debian 9

I am using Debian 9, 64-bit.
I am trying to install the Snap version of Skype on my PC but when I click on the green icon it tells me that it does not understand the file format.
Is there something that I need to do before installing the Snap version of Skype?

Try this command line way:

sudo apt install snapd
snap install skype --classic

Will your instructions allow me to install the Snap version of Skype, or will I be installing some other version located in the Debian repository?
I imagine that the Snap version of Skype is more recent. I could be wrong…

snap install ... will obviously install a snap package :wink:

Thank you popey and ogra for your help!
