Just for the record. The «PDF Chain» message for an «input.pdf» PDFTK returned error! Input/Output Error Error code: 256
may be removed by decrypting «input.pdf» with the command qpdf --decrypt input.pdf output.pdf as Manoj did for another, related problem https://stackoverflow.com/questions/30259554/pdftk-error-failed-to-open-pdf-file. Nothing in the PDF file's cover says "encrypted", it says "optimized". So compression was applied and it needs to be decompressed for PDFTK to open it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1048045 Title: PDF Chain error 256 when attempting to concatenate PDF files To manage notifications about this bug go to: https://bugs.launchpad.net/pdfchain/+bug/1048045/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
