I downloaded and installed an early testing image using antiX with a new image that utilizes Debian's Bullseye Alpha.
I also downloaded the Debian Alpha 3 build and installed it. The antiX one was super easy. The one I got from Debian was fine too, much bigger in size, took a while to copy, load, and install. It also took me three attempts because the first two builds did not include the "non-free" wireless firmware that most distributions include. I was careful to look for the "non-free" Debian 64-bit builds; then I was successful; I never have those problems when I install antiX or MX Linux, and I usually don't have problems when I get the right Debian images; guess it's been a while and I'm getting "rusty" at remembering the details; I guess it is because I run these things for a couple of years and sometimes forget the details needed to get it right the first time! Anyway, both Debian and antiX have at least one new build based off an early "Alpha" testing phase and the good news is that they both work fine.
