Epson Perfection V30 didn't work, and I've gotten it working now. Had these problems on 17.10, almost b0rked my system with some of the proposed solutions re downgrading. Here's what worked today (Dec 13, 2017) on a fresh install:
*Before* installing iscan-data, iscan, and esci-interpreter-gt-f720 from the Epson package, I made a symlink from /usr/lib/x86_64-linux-gnu/sane to /usr/lib/sane so things would get to the right place automatically. (This might be a further useful fix to add to the libsane package.) Then I installed the software from the Epson package. Then I followed the instructions on <a href="https://help.ubuntu.com/community/sane#Setting_up_SANE";>the community site</a>. I tried XSane, and it wouldn't detect my scanner. I added an 'epkowa' line to /etc/sane.d/dll.conf, and after that, I could run 'sane-find-scanner' as root successfully, and running 'scanimage -L' as root activated the scanner. I was able to run gscan2pdf (my preferred app) as root successfully, and used it to scan a document. Of course, I don't want to run this software as root every time. So then I created the 79-udev-epson.rules file per <a href="https://bugs.launchpad.net/ubuntu/+source/sane- backends/+bug/1707352/comments/86">comment 86</a>, rebooted, and everything works now as a regular user.
