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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899667 Title: LO can't send email, probably an apparmour problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kmail/+bug/1899667/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
