As a workaround I downloaded libpoppler58 .deb and the libpng12 .deb which it required, then put them in the same folder and ran from that folder in terminal...
sudo dpkg -i libpoppler58_0.41.0-0ubuntu1.1_i386.deb libpng12-0_1.2.54-1ubuntu1_i386.deb ...before attempting to install Inkscape stable again which succeeded. Please note, my architecture is i386 and yours may be different, so download the correct matching .debs for your platform. I searched for Xenial packages in each case. Seems libpoppler58 can live alongside libpoppler61 if necessary - nothing needed to be downgraded or uninstalled that I could see and Inkscape stable seemed to launch and run OK after this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1638373 Title: End marker/start marker drop-down menus are empty To manage notifications about this bug go to: https://bugs.launchpad.net/inkscape/+bug/1638373/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
