I just installed kubuntu 18.04 (minimal install) in a 64bits VM, then installed libreoffice, and all programs in the suite start and work as expected.
The backtrace suggests that the issue has to do with OpenGL initialization. Can you try the instructions at https://wiki.documentfoundation.org/OpenGL#Crash_on_program_start to disable hardware acceleration in libreoffice, and report whether this makes the crash go away? ** Changed in: libreoffice (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768756 Title: Libreoffice 6 does not start on Kubuntu 18.04 (clean install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1768756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
