These instructions are for Ubuntu 18.04 and will fail on 18.10 with the error “The repository does not have a Release file.”
These instructions are for upgrade from Ubuntu 18.04 -> 18.10. Please provide more information regarding this error.
It worked for me on Ubuntu 18.10 without any extra effort.
