dotfiles/ubuntu.md

Document Roadmap

• oh-my-zsh install
• ssh setup from vimwiki
• git clone dotfiles
• cd dotfiles and run makefile
  • (make toplevel rules, i.e setup_nerdfonts is a sub of setup_alacritty)

Intro

This post-install script is intended to be run directly after ubuntu 22.05 installion. The scipt assumes device is encrypted and user account is protected. With a strong passphrasses for both. Open terminal, run one code snippet at the time and check that no errors occur:

apt package

startup installation for ubuntu clients

# add external repos
sudo add-apt-repository ppa:aslatter/ppa    # for alacritty

sudo apt install git -y           # version control
# sudo apt install neovim -y      # brew install nvim to get version 0.7
# sudo apt install librewolf -y   # add librewolf repo first
sudo apt install qutebrowser -y   # minimal vim-binding browser
sudo apt install gnome-tweaks -y  # tool to remap caps to ctrl
sudo apt install alacritty -y     # add alacritty repo first
sudo apt install tmux -y          # terminal multiplexer
sudo apt install make -y          # utility to maintain shell program groups
sudo apt install curl -y          # file transfer helper
sudo apt install ffmpeg -y        # audio/video converter
sudo apt install keepass2 -y      # password manager
sudo apt install zsh -y           # install oh-my-zsh to set zsh as default shell

# music setup
sudo apt install mpd -y           # music player daemon
sudo apt install ncmpcpp -y       # ncurses music player controller plus plus

Now install oh-my-zsh and reboot.

ssh setup

🚧 under construction

no-prompt ssh keys https://stackoverflow.com/a/43235320

Setup ssh key for github

The first ssh key is generated for github:

ssh-keygen -q -t ed25519 -N '' -f ~/.ssh/id_ed25519_github <<<y >/dev/null 2>&1

# older machines might not support ed25519, then use RSA with 4096 bit key
# ssh-keygen -q -t rsa -b 4096 -N '' -f ~/.ssh/id_rsa_github <<<y >/dev/null 2>&1

Log in to github. Go to github.com/settings/ssh/new. Enter a title format in the format 2022-homeserver. Enter the key returned by cat ~/.ssh/id_*_github.pub. Now you can clone your private repos and make changes to your public repos.

Setup ssh key for connecting to other servers

This next ssh key is generated for internal servers:

ssh-keygen -q -t ed25519 -N '' -f ~/.ssh/id_ed25519_mynetwork <<<y >/dev/null 2>&1

# older machines might not support ed25519, then use RSA with 4096 bit key
# ssh-keygen -q -t rsa -b 4096 -N '' -f ~/.ssh/id_rsa_mynetwork <<<y >/dev/null 2>&1

The public ssh key is in ~/.ssh/id_*_mynetwork.pub. Copy the public key to machines which you want to access with this machine. Inversely, if you want other machines to ssh to this machine, copy their public keys to this machine.

ssh resources

• Digital Ocean ssh essentials

server-side setup checklist

• setup locales (LC_LANGUAGE, LC_ALL)
• install openssh-server
• enable ssh service on startup
• copy workstation public key to server
• ssh via key (i.e no password)
• disable password authentication

Snap packages

snap install codium --classic

Homebrew packages

Install brew and brew install:

brew install yt-dlp
brew install neovim
brew install lf

Mail & Calendar

Use thunderbird to attach to just about any mail + cal clients

Password Manager

• Start using keepass
• Research version controlling DB
• Start using a secret file to unlock DB
