Yes the installation steps are broken, the easiest way to reproduce is just start clean Ubuntu 16.04 and go step by step with HOWTO doc. I was able to fix the issue by installing various python dev related stuff, cannot tell with exactly was the case. This is quite sad the issue was not resolved since 2014. There could be a CI setup to start electrum-server in regtest mode.
