I install, run and update via this container script [1] on Arch. It works very well.

This aur package [1] works well for me. Unfortunately the new maintainer removed the automatic download and you need to manually download the zip via the form on Blackmagic's website (however not even the email is validated).

This is a good place to share that MakeResolveDeb makes installing Davinci Resolve very easy on Ubuntu/Mint/Debian

Way more people should know about this solution.

That's the experience on CachyOS. They package it up for their users and updates just work.

    pacman -S davinci-resolve
