dotfiles

André Milton's dotfiles, managed with chezmoi.io.

Preflight

You'll need to have an ssh key and gpg keys set up in Github. The initialization will ask for the gpg key ID (see List Keys below).

Install

Ubuntu

To install on Ubuntu 20.04:

snap install chezmoi --classic
systemctl stop apt-daily.timer
sudo apt-get install git
chezmoi init --apply --verbose https://github.com/Wred/dotfiles.git

Note: the stop for the apt service seems necessary to remove the lock likely taken by auto-update before installing git

Arch

To install on Manjaro-i3 (https://manjaro.org/downloads/community/i3/):

pacman -S --noconfirm chezmoi
chezmoi init --apply --verbose https://github.com/Wred/dotfiles.git

Mac

To install on MacOS, install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Follow the instructions to add brew to the path etc.

Install gpupg with brew to generate a key (see below) and don't forget to generate an ssh key and add to Github. You'll also need to fix the gpg config to point to gpg-agent to the correct pinentry (see https://stackoverflow.com/questions/39494631/gpg-failed-to-sign-the-data-fatal-failed-to-write-commit-object-git-2-10-0):

echo "pinentry-program $(brew --prefix)/bin/pinentry-mac" >> ~/.gnupg/gpg-agent.conf
killall gpg-agent

Install chezmoi:

brew install chezmoi
chezmoi init --apply --verbose git@github.com:Wred/dotfiles.git

Postflight

Install the tmux packages using prefix-I to start the tpm install. Set the Neovim theme with <leader> th.

GPG

Using GPG for signing commits in git.

Create keys

You can do this on a new machine:

gpg --full-generate-key

Backup keys

gpg --armor --export > pgp-public-keys.asc
gpg --armor --export-secret-keys > pgp-private-keys.asc
gpg --export-ownertrust > pgp-ownertrust.asc

Restore keys

gpg --import pgp-public-keys.asc
gpg --import pgp-private-keys.asc
gpg --import-ownertrust pgp-ownertrust.asc

List keys

Public keys:

gpg -k --keyid-format LONG

Private keys:

gpg -K --keyid-format LONG

Note: the ID is only listed in LONG format (after the slash)

Add keys to Github account

To output the ASCII armor format to copy/paste into Github:

gpg --armor --export KEYID

Renewing keys

GPG keys expire (set when you create them). To renew, find the key and edit:

$ gpg --list-keys
$ gpg --edit-key KEYID

Use the expire command to set a new expire date:

gpg> expire

When prompted type 1y or however long you want the key to last for.

Select all the subkeys (the primary key, which we just set the expires date for, is key 0):

gpg> key 1
gpg> key 2
gpg> expire

A star will sppear before all selected keys.

Since the key has changed we now need to trust it, otherwise we get the error "There is no assurance this key belongs to the named user" when using they key:

gpg> trust

When done, save:

gpg> save

Test key

Test it out, do a round trip:

gpg -ea > secret.out
gpg -d secret.out

Key mapping

Ubuntu

Had a hell of a time finding a way to map escape and control to capslock on linux and include it in this dotfiles repo. So for now just do it manually from here:

https://github.com/rvaiya/keyd

Add a file /etc/keyd/default.conf:

[ids]

*

[main]

capslock = overload(control, esc)

Windows
