After the installation on Krop following this .deb instructions:

$   sudo apt-get install python3-poppler-qt5, python3-pypdf2 $   sudo dpkg -i krop_0.5.1-1_all.deb 

I have the message :

Traceback (most recent call last): File "/usr/local/bin/krop", line 18, in <module> main() File "/usr/local/lib/python2.7/dist-packages/krop/application.py", line 65, in main from krop.mainwindow import MainWindow File "/usr/local/lib/python2.7/dist-packages/krop/mainwindow.py", line 39, in <module> from krop.vieweritem import ViewerItem File "/usr/local/lib/python2.7/dist-packages/krop/vieweritem.py", line 33, in <module> raise RuntimeError(_msg) RuntimeError: Please install popplerqt4 first. On recent versions of Ubuntu, the following should do the trick: sudo apt-get install python-poppler-qt4 (or, if using python3) sudo apt-get install python3-poppler-qt4 

I can’t install python-poppler-qt4 nor python3-poppler-qt4, apt doesn’t find them. Iven don’t know if it is usefull, because python3-poppler-qt5 is installed.
