Installing Electrum on an air-gapped Ubuntu Machine

This guide shows how to install Electrum on an air-gapped machine. You will also need an Ubuntu machine connected to the network in order to complete this guide (it can be a virtual machine).

On the online machine

If you are running Ubuntu 16.04 off of a live USB, there is a bug that affects the package manager. You need to run these two commands at the terminal to fix it:

$ sudo mv /var/cache/app-info/xapian/default /var/cache/app-info/xapian/default_old

	mkdir ~/vim
	cd ~/vim

	# Staically linked vim version compiled from https://github.com/ericpruitt/static-vim
	# Compiled on Jul 20 2017
	curl 'https://s3.amazonaws.com/bengoa/vim-static.tar.gz' \| tar -xz

	export VIMRUNTIME="$HOME/vim/runtime"
	export PATH="$HOME/vim:$PATH"
	cd -

	# Enable Packetization Layer Path MTU Discovery.
	net.ipv4.tcp_mtu_probing = 1
	net.ipv4.tcp_base_mss = 1024

	# Ensure slow start is disabled
	# https://github.com/ton31337/tools/wiki/tcp_slow_start_after_idle---tcp_no_metrics_save-performance
	net.ipv4.tcp_slow_start_after_idle = 0
	net.ipv4.tcp_no_metrics_save = 0

	# Tune network buffers - servers have more than 16MB of RAM in 2017
