Hi all, long time Windows guy over here and a noob with Linux. I’m trying to install Electrum on an offline computer running Ubuntu 16.04, while I have watch-only wallet on different (online) computer. I had no problems setting up Electrum on the online computer, but I can’t get it installed on the offline computer.
I copied over Electrum-2.8.2.tar.gz (in my Home Downloads directory) and untarred it. In the Electrum directory, I ran: ‘
python electrum’. That resulted in the following error:
“Error: Could not import PyQt4 on Linux systems, you may try ‘sudo apt-get install python-qt4’.”So I ran ‘
sudo apt-get install python-qt4’, but then got
“unable to locate package python-qt4”.After searching around, it’s my understanding that I have to download and install python-qt4 (as well as python-pip?), which lead me to
http://pyqt.sourceforge.net/Docs/PyQt4/installation.html... but then my nooby eyes started crossing.

Is there an easier way of installing Electrum and its dependencies on this offline computer?
Or, alternatively, would it be considered less secure (in a cold storage setup) to simply have this machine connected online just for the initial Ubuntu and Electrum installation phase, and once installed, disconnect it from the network forever after that, to sign transactions?
Thanks!
