Hey, going through practicalli spacemacs setup on ubuntu 22.04, thanks for the great work!
I just want to highlight a couple additional steps I had to perform which may be worth adding:
1. In spacemacs, install https://github.com/rainstormstudio/nerd-icons.el#installing-fonts via SPC SPC nerd-icons-install-fonts
2. (Optional) To make https://github.com/akermu/emacs-libvterm#requirements on Ubuntu 22.04 I had to install these additional packages: cmake, libvterm-bin, libtool-bin. In spacemacs compilation can be triggered with SPC SPC vterm-module-compile
