Can't install on Ubuntu 19.04

This is the error I get when running make.

Please cease whatever you are doing, and head over to the page for devkitPro pacman. It looks like you need to sudo dkp-pacman -Syu in order to update your toolchain (devkitA64) installation. You are also strongly advised against trying to build libnx on your own; and instead please use the pre-built stable package we provide through pacman.

Thank you!
