gscan2pdf v2.5.6 released

[Mikhail Novosyolov]

pdftk was removed from Debian repos when Ubuntu 18.04 was branched and 
then a new implementation in Java was added to Debian repos and appeared 
only after Ubuntu 18.04. Download pdftk deb from packages.ubuntu.com 
from Ubuntu 16.04 xenial and install it in 18.04

P.S. I had thoughts to build pdftk for Ubuntu 18.04 in my PPA. Which PPA 
did you install gscan2pdf from?
