I installed from zesty-desktop-i386.iso (without fetching any proprietary packages). After rebooting into the installed system I could install flashplugin-installer (and the whole lubuntu-restricted-extras).
It seems this bug affects only the installation of Lubuntu itself, or maybe it is depending on the hardware. I installed in http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/
