I just tried the suggestion above by Erik Johnson, but it didn't help.

# pdfshuffler

I also tried with a symbolic link, but it broke in the same way:

# cd /usr/lib/python2.7/site-packages/
# ln -s PyPDF2 pyPdf
# pdfshuffler 
/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display

It seems to me that the API between pyPdf and PyPDF2 is different.

This is unrelated to pyPdf / PyPDF2 imo. The log sys that it has trouble opening a display, so rather GTK related. 
Maybe check if the DISPLAY environment variable is set correctly (echo $DISPLAY). Maybe you are trying this over SSH? Have you tried running pdfshuffler via the launcher?

BTW: I would recommend everyone to have a look at pdfarranger, it's better supported, Python3, GTK3 and PyPDF2 by default.

I am seeing the same problem on a Fedora 29 KDE Plasma Spin that has been upgraded to Fedora 30 before installing "pdfshuffler".  On a machine where I installed "pdfshuffler" under Fedora 29 (KDE Plasma Spin) and then upgraded to Fedora 30, "pdfshuffler" works just fine.  Looking at the machine where "pdfshuffler" was installed under Fedora 29 (before the upgrade) the old dependency was installed under Fedora 29 and is still there ("pyPdf-1.13-16.fc29.noarch").

On the machine where "pdfshuffler" was installed after the upgrade to Fedora 30, running "pdfshuffler" from the command line, I get:

Error: Could not import pdfshuffler
Cause: No module named pyPdf

Looking for pyPdf using "dnf list *pyPdf*", I get:

$ dnf list *pypdf*

Summary     : PDF file merging, rearranging, and splitting
Description :
PDF-Shuffler is a small python-gtk application, which helps the user
to merge or split pdf documents and rotate, crop and rearrange their
pages using an interactive and intuitive graphical interface.
/usr/bin/python2
pygtk2
pypoppler
python(abi) = 2.7
python2-PyPDF2
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PartialHardlinkSets) <= 4.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
rpmlib(PayloadIsXz) <= 5.2-1

It looks like the python2-PyPDF2 is installed, but it still doesn't run.

Applying Erik Johnson's fix above worked for me, so /usr/lib/python2.7/site-packages/pdfshuffler/pdfshuffler.py looks like it needs to be updated and the RPM's dependencies are actually OK.

This seems to be a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1592820 , which might resolve the issue.

*** Bug 1708993 has been marked as a duplicate of this bug. ***

This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

pdfshuffler will be replaced by pdfarranger.

*** Bug 1765781 has been marked as a duplicate of this bug. ***

As a temporary and easy workaround you could just install the missing package.

    pip2 install pyPdf

I did this, because pdfarranger takes very long to start.
