I'm not quite sure why it needs a snap.
Anyway when I try it says:
snap install skype
error: This revision of snap "skype" was published using classic confinement and thus may perform
arbitrary system changes outside of the security sandbox that snaps are usually confined to,
which may put your system at risk.
If you understand and want to proceed repeat the command including --classic.
NnNnooOOO!!!!!DON'T DO IT!!!!!!
I have Skype on my Ubuntu machine (this one) but Skype crashes within five seconds of logging in,so I've gone back to good ol' Google Hangout.
Definitely wouldn't use until they upgrade the confinement.
