Unsigned Repo Error

[1alan1]

About a month ago I started to notice that some of my updates would fail to install, up to 41 now.
The error flashes up and it says something about failing and unsigned repo's. I have not changed anything as far
as software sources. I am not sure what it wants.

Thanks!

You need to add the gpg key for Skype's repo like so:
(from https://repo.skype.com/)

run: this command in a terminal:

curl https://repo.skype.com/data/SKYPE-GPG-KEY | sudo apt-key add -

He often is... and so are Snowhog, Vinny, Dibl, Acheron(sp?) GreyGeek, jlittle, oshunluvr, and many more I can't remember off the top of my head. You can't beat the signal to noise ratio hereabouts.
