The same happens on Ubuntu Gnome versions. It looks like apparmour problem. I did next steps to make it work:
ln -s /etc/apparmor.d/usr.lib.libreoffice.program.oosplash /etc/apparmor.d/disable/ apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.oosplash ln -s /etc/apparmor.d/usr.lib.libreoffice.program.soffice.bin /etc/apparmor.d/disable/ apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.soffice.bin ln -s /etc/apparmor.d/usr.lib.libreoffice.program.senddoc /etc/apparmor.d/disable/ apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.senddoc And after that I had to replace sensible-lomua with thunderbird inside LO Tools -> Settings -> Internet -> E-mail client. I don't know why sensbile-lomua does not exist anymore and nothing else works. Even if I put xdg-email or just thunderbird. Without apparmor changes it does nothing. -- 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/1899667 Title: LO can't send email, probably an apparmour problem Status in kmail package in Ubuntu: Confirmed Status in libreoffice package in Ubuntu: Confirmed Bug description: LO can't send email: LibreOffice was unable to find a working email configuration. I'm pretty sure this is an apparmour profile problem since LO seems to want RW perms on something and AA seems not to want to give it.
