How to Install GScan2PDF 2.2.0 release on Ubuntu 18.04

    gscan2pdf is a GUI to ease the process of producing PDFs or DjVus from scanned documents. You scan one or several pages in with File/Scan, and create a PDF of selected pages with File/Save PDF. At maturity, the GUI will have similar features to that of the Windows Imaging program, but with the express objective of writing a PDF, including metadata. Scanning is handled with SANE via scanimage. PDF conversion is done by libtiff. Perl is used for portability and ease of programming, with gtk2-perl for the GUI. This should therefore work more or less out of the box on any system with gtk2-perl, scanimage, and libtiff.

• Check validity of device blacklist regex when applying preferences
• Modify preference “Force new scan job between pages” to only take effect when scanning from flatbed.
