Need to install 64-bit Ubuntu

[rhyde]

I wrote up a mostly step by step tutorial for the Ubuntu Focal (20.04) install process with 5.7 kernel and such.

It's a pure 64-bit install, but you can easily create a 32-bit chroot to test 32-bit software in there as well.  I've got a 32-bit Ubuntu install for media browsers (Spotify and crew - the DRM modules for ARM are 32-bit only).

For testing, though, there's really no reason to put the install on the eMMC.  Just use the install on the SD card - update the kernel if you want, but you should be ~fine once you boot from the SD card with the image on it (I think it's a 5.6 kernel without all the hardware acceleration, but that's fine for testing builds).

Yeah, I tried installing that version already (on SD Card). I created the SD Card using Etcher on macOS. When I attempt to boot off the card the screen goes black and nothing ever happens (even after several minutes). Power LED switched from orange to green and the screen flashed for a brief moment. But that was it.

Oh well, as I said I got Swift working on Manjaro, which is what I needed Ubuntu for; so I'm good.
Perhaps at some point in the future I'll revisit this. I really prefer Ubuntu and Debian distributions (and the apt-style updates and package management).
