You're using the Ubuntu 19.04 instructions, but actually the Ubuntu 18.04 instructions are more likely to work on Linux Mint 19.1. We don't have dropdown entries for some distros and there's no easy way to figure this out on your own, sorry about that. Someone else hit this problem earlier at #2836.

(#2576 is tracking making this clearer somehow.)
