Bootstrap Ubuntu

My rough notes on bootstrapping a plain Ubuntu instance into my dev environment.

Prequisites

• Ubuntu 22.04 (I use Ubuntu MATE)
• My user with sudo permissions

Install any updates.

1
2

sudo apt-update
sudo apt-upgrade

Remote Access

• Pin the IP address
• Install an SSH server
• Add my public key
• Verify SSH access

Pin the IP address

Currently my internal network is managed by [eero].

Verify that, if using WiFi, that I’m connected to the correct WiFi network.

• Open [eero] app on phone
• Settings
• Network Settings
• Reservations & port forwarding
• Add a Resrvation
• Select device
• Save

Install an SSH server

1

sudo apt install openssh-server molly-guard

Assuming the hostname is anker with an IP address of 192.168.2.22:

Add host details to ~/.ssh/config:

1
2
3

Host anker
    Hostname 192.168.2.22
    User pcampbell

Test that you can ssh to the server:

1

ssh anker

Exit and return to the local machine.

Add my public key

Add public key to server:

1
2

ssh-copy-id -i ~/.ssh/id_rsa anker
ssh-copy-id -i ~/.ssh/id_ed25519 anker

Verify SSH access

Verify that you don’t need to enter your password (assuming your ssh-agent is working):

1

ssh anker

Configure home directory

I use [yadm] to track my user settings, although I want to have a look at [chezmoi] as a possible alternative.

• Install rust, rtx and yadm
• Clone yadm dotfiles
• Verify submodules
• Verify ssh access retained
• Verify neovim config loaded

Install rust, rtx and yadm

Run the following commands on the server.

Rust

1
2

sudo apt install curl git direnv keychain
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | shcurl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Quit and restart ssh and verify ~/.cargo/bin/ is in your PATH.

RTX

1

cargo install rtx-cli

Note, when using NuShell, I’m not able to run rtx without specifying the full path, ~/.cargo/bin/rtx.

• See: https://github.com/jdxcode/rtx/issues/514

Yadm

1
2

rtx global yadm@latest
rtx install

Now clone the yadm dotfiles repo:

$(rtx which yadm) clone --depth 1 --recursive git@git.kemitix.net:kemitix/dotfiles-yadm.git 
$(rtx which yadm) checkout $HOME
$(rtx which yadm) enter
git submodule update --init --recursive
cd ~/.config/nvim/lua
ln -s ~/.config/nvim-lua-user/ user
exit
rtx install

Boostrap

Run the bootstrap:

1

~/bin/bootstrap all

Install Desktop software

If using the machine as a desktop.

• Vivaldi
• Thunderbird

Install Docker

These are the instructions from docker.com
