I have the same version of LibreOffice installed. The problem is not only with exporting PDF to a network drive, but also with trying to "Save As" to the same drive. If I change the document and simply "Save" it, it works well.
I do not use the Libreoffice dialog box to access the network drive, I connect to it through Nautilus "Connect to server: davs://<>" etc. and then access it through Nautilus and open the document by double- clicking. I had similar problem once after distro upgrade, I believe this bug is related to it: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1069757 -- 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/1826468 Title: Libreoffice Calc cannot export PDF to a network drive Status in libreoffice package in Ubuntu: Incomplete Bug description: After upgrading from 18.10 to 19.04 I lost possibility to export a document to PDF, if a document is on a network drive (it's a DAVS network folder in my case).
