Seems to be a widely shared issue across milestones. 'URE' documentation shows that Ubuntu does not follow the main common path "By default, the URE is installed in /opt/libreoffice/ure on Linux" https://github.com/LibreOffice/core/tree/master/ure/source
It should be good if Canonical LO team pay attention to such problem. Sadly Lo reports on Launchpad seems reported and then ignored most of the time. and other similar problem related to 'ure' lp:1592071 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1680336 Title: libreoffice java based extension cannot find java_uno due to wrong java.library.path Status in libreoffice package in Ubuntu: Confirmed Bug description: I try to use the "E-Porto Add In" (extension to insert a stamp for the German postal system) from https://www.deutschepost.de/de/i /internetmarke-porto-drucken/e-porto-add-in.html on Ubuntu 16.04 amd64.

With libreoffice --strace I found out that actually it cannot find the libjava_uno.so library. I found a workaround by creating the /usr/lib/libreoffice/program/ooenv file with export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/libreoffice/program/classes:/usr/lib/libreoffice/program in it. This issue has been also discussed on UbuntuUsers.de: https://forum.ubuntuusers.de/topic/e-porto-add-in-libreoffice-5-1-6-2 -kein-login-/ Can you please improve libreoffice / ure so that it will set the library path correctly without user intervention?
