Sharing some findings after having poked a bit to the issue, the problems come from the /usr/lib/libreoffice/share/registry/main.xcd configuration, copying that file from the Debian build makes the documentation open in the default webbrowser and work.
The Ubuntu version is having no mention of DesktopBackend which seems relevant The build log has those warnings which don't exist in Debian or Bionic '... no obvious way to instantiate implementation "com.sun.star.comp.configuration.Update" no obvious way to instantiate implementation "com.sun.star.comp.configuration.backend.DesktopBackend" no obvious way to instantiate implementation "com.sun.star.comp.configuration.backend.KF5Backend" ...' They seem to come from tests and probably not the direct but could hint on an issue, if the backend fails to load then it could end up missing from the configuration There is nothing obvious in the packaging diff between Debian and Ubuntu though... Including the Debian file so it's easier for other to check the differences / test if it works for them as well by copying it over the system one -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869561 Title: Libreoffice Help does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1869561/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
