I just reinstalled my machine from Ubuntu 16.04 to 20.04. I'm using i3wm for a few years, and things never worked out of the box. The sound applet, VPN, and other small things that quickly add up.
I'm now using Regolith [1] and loving it. It offers a clean and neat i3wm installation, but still uses Ubuntu's system admin tools. It was really simple to install: just install Ubuntu, add its PPA and run apt-get.
I highly recommend it for anyone that likes i3wm but doesn't want to be fiddling with configuration files to connect to a new WiFI or pair bluetooth headphones.
