I would like to install the bitcoin client Electrum on an offline live USB drive. This would help to create and restore wallets most securely.
The install instructions are as follows:
Install python-qt4 and pip:
sudo apt-get install python-qt4 python-pip
sudo pip install http://download.electrum.org/Electrum-1.8.1.tar.gz#md5=dc9f4b1cb38bd1d152be83d0a430cf62
What would be the way to do this offline?
The packages can obviously be downloaded and copied to the USB drive. However, I can't get python-qt4 to install. There is a related question, but I don't understand how to go through this.
