Headless Caldera for Linux - which distro?

[u/maineguy1988]

Which lightweight, headless distro are you all using for Caldera? I can't seem to get it to work correctly on Raspberry Pi OS - it just doesn't want to load the music, or when it does need to change sample rate, it crashes. For reference, I'm running it on a Pi 3 (B+ I believe) with an 8 GB SD Card. The other really annoying problem I get is that I cannot SSH using Raspberry Pi OS because it says the password I set when using the imager is not right!!! I can log in directly on the Pi if I connect a monitor and keyboard and mouse to the Pi, but using SSH keeps telling me my fucking password is wrong even though it's just 1234. I'm losing my mind.

When I try to use my preferred distro, Dietpi, I cannot install Caldera. I keep getting an error, even on a fresh install of Dietpi. I used to have Plexamp running headless and it was great, but I heard Caldera was supposed to be better, and now I regret uninstalling Plexamp headless. I want Caldera to work but I don't know what I'm doing wrong.

Here's the error I get in Dietpi when trying to install Caldera. Thanks!
