Today I have tried to install pdftk on ubuntu 18 . After search on developer site I saw that are package only for the redhat/centos.

So after a few search find out that you can install it with snap install pdftk

However this will not work .

Error: Unable to find file.
Error: Failed to open PDF file:
Errors encountered. No output created.
Done. Input errors, so no output created.

Errors like this you will see.

One solution is to download and install from other links

cd /tmp
# download packages
wget http://launchpadlibrarian.net/340410966/libgcj17_6.4.0-8ubuntu1_amd64.deb \
 http://launchpadlibrarian.net/337429932/libgcj-common_6.4-3ubuntu1_all.deb \
 https://launchpad.net/ubuntu/+source/pdftk/2.02-4build1/+build/10581759/+files/pdftk_2.02-4build1_amd64.deb \
 https://launchpad.net/ubuntu/+source/pdftk/2.02-4build1/+build/10581759/+files/pdftk-dbg_2.02-4build1_amd64.deb

And after that you can install them with 
sudo apt-get install ./libgcj17_6.4.0-8ubuntu1_amd64.deb \
    ./libgcj-common_6.4-3ubuntu1_all.deb \
    ./pdftk_2.02-4build1_amd64.deb \
    ./pdftk-dbg_2.02-4build1_amd64.deb

After that you can remove those from /tmp directory
