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?

Hi Jeff,
I have installed it on Ubuntu from PPA.
After Start it says, that package pdftk is missing, but I can not
install it with:
sudo apt install pdftk

gscan2pdf - A GUI to produce a multipage PDF or DjVu from a scan.
http://gscan2pdf.sourceforge.net/
Five clicks are required to scan several pages and then save all or
a selection as a PDF or DjVu file, including metadata if required.
gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via
libimage-sane-perl, scanimage or scanadf, and can scan multiple pages at
once. It presents a thumbnail view of scanned pages, and permits simple
operations such as cropping, rotating and deleting pages.
OCR can be used to recognise text in the scans, and the output
embedded in the PDF or DjVu.
PDF conversion is done by PDF::API2.
The resulting document may be saved as a PDF, DjVu, multipage TIFF file,
or single page image file.
