I'm getting an error message that the upgrade process tells me I'm supposed to fix before it can continue, but I don't know how to fix it.
This is the 'E' message: The repository 'https://repo.skype.com/deb stable InRelease' is not signed.
Immediately before this message is a 'W'arning message about a related GPG error. (I don't know what GPG is either.) Edit: I found out what GPG is.
I don't have Skype installed, so I'm not sure why this would even be a problem.
