Thanks for the information. Your pdf file is probably encrypted with AES (supported since PDF 1.6) which is (still) not yet supported in pdftk. The real bug is that pdftk does not detect, that it does not support it.
To circumvent the problem, you can open it with a viewer and print it into a new pdf file - or replace pdftk with other tools. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1191381 Title: pdftk password decryption doesn't work [missing AES support] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pdftk/+bug/1191381/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
