Tried Kubuntu, but now I'm back on Ubuntu, because I don't like Dolphin, Nautilus won btw. (I tried installing it on KDE but then it downloaded all of GNOME so might as well just use GNOME).

Here is my post-install "guide", what am I missing?

sudo apt install qbittorrent && sudo snap install keepassxc code anki-desktop obsidian mpv tailscale && sudo snap remove firefox

Librewolf:
sudo apt update && sudo apt install extrepo -y && sudo extrepo enable librewolf && sudo apt update && sudo apt install librewolf -y

sudo tailscale up --exit-node=name --exit-node-allow-lan-access

I know this is where NixOS would shine, but home-manager and flakes filtered me.
I'm going to try use things as default as possible without tinkering basically.
