I've tried compiling from latest Git source of LibreOffice as to their instructions; everything else seems to compile pretty much OK, but alas; the same 'com::sun::star::uno::Sequence' is there to haunt during the compile -- it registers as a "warning" rather than an "error", so that's why it's probably passed on to pre-compiled binaries.

Perhaps this needs a closer look? -- 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/1922112 Title: libreoffice (var. versions under v.7.x) on arm64, terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException' \ Fatal exception: Signal 6 Status in libreoffice package in Ubuntu: New Bug description: Hi there, I've had the recurring problem on multiple 64-bit Ubuntu installations on multiple Raspberry Pi 4B's [aarch64/arm64] where libreoffice crashes on startup -- this seems to be a persistent bug, as it has happened to me on 20.04 LTS (arm64) as well as more recently on 20.10 groovy (arm64), whether I've used the official APT packages or the LibreOffice Launchpad PPA's. I've tried looking around for the bug and for example, deleted the existing user config etc. -- to no avail. As for the window manager, I'm running on Xubuntu (Xfce/Xfwm4) and with the latest available upstream kernel (5.8.0.1020-raspi), although LibreOffice crashing on startup has been a persisting problem on my RPi4B Ubuntu installations for quite some time now, probably around a half a year or so. Every now and then, as the apt packages get updated, LibreOffice actually works (!), so that's kind of odd. Here's the error message I get (same crash applies for all other libreoffice executables that I've tried): $ libreoffice terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException' Fatal exception: Signal 6 Stack: /usr/lib/libreoffice/program/libuno_sal.so.3(+0x3c850)[0xffffb3f50850] /usr/lib/libreoffice/program/libuno_sal.so.3(+0x3c9ec)[0xffffb3f509ec] linux-vdso.so.1(__kernel_rt_sigreturn+0x0)[0xffffb85805d8] /lib/aarch64-linux-gnu/libc.so.6(gsignal+0xdc)[0xffffb3d7ce9c] /lib/aarch64-linux-gnu/libc.so.6(abort+0xf4)[0xffffb3d6950c] /lib/aarch64-linux-gnu/libstdc++.so.6(_ZN9__gnu_cxx27__verbose_terminate_handlerEv+0x1a8)[0xffffb135f888] /lib/aarch64-linux-gnu/libstdc++.so.6(+0x9f1dc)[0xffffb135c1dc] /lib/aarch64-linux-gnu/libstdc++.so.6(+0x9f240)[0xffffb135c240] /lib/aarch64-linux-gnu/libstdc++.so.6(+0x9f534)[0xffffb135c534] /usr/lib/libreoffice/program/libmergedlo.so(+0x116b51c)[0xffffb50f251c] /usr/lib/libreoffice/program/libmergedlo.so(+0x116bbc4)[0xffffb50f2bc4] /usr/lib/libreoffice/program/libmergedlo.so(+0x116c228)[0xffffb50f3228] /usr/lib/libreoffice/program/libmergedlo.so(+0x116ccd4)[0xffffb50f3cd4] /usr/lib/libreoffice/program/libmergedlo.so(+0x11709fc)[0xffffb50f79fc] /usr/lib/libreoffice/program/libmergedlo.so(+0x2c4b6e0)[0xffffb6bd26e0] /usr/lib/libreoffice/program/libmergedlo.so(+0x2c4be68)[0xffffb6bd2e68] /usr/lib/libreoffice/program/libmergedlo.so(_ZN3utl10ConfigItemC2ERKN3rtl8OUStringE14ConfigItemMode+0x78)[0xffffb6bca33c] /usr/lib/libreoffice/program/libmergedlo.so(+0x2c905c8)[0xffffb6c175c8] /usr/lib/libreoffice/program/libmergedlo.so(_ZN19SvtSysLocaleOptionsC1Ev+0x124)[0xffffb6c18b54] /usr/lib/libreoffice/program/libmergedlo.so(+0x30956a4)[0xffffb701c6a4] /usr/lib/libreoffice/program/libvclplug_gtk3lo.so(+0xd8928)[0xffffad5e0928] /usr/lib/libreoffice/program/libvclplug_gtk3lo.so(+0xda1d4)[0xffffad5e21d4] /usr/lib/libreoffice/program/libvclplug_gtk3lo.so(+0xea218)[0xffffad5f2218] /usr/lib/libreoffice/program/libmergedlo.so(_Z7InitVCLv+0x4a0)[0xffffb7029d60] /usr/lib/libreoffice/program/libmergedlo.so(_Z10ImplSVMainv+0xf8)[0xffffb702b468] /usr/lib/libreoffice/program/libmergedlo.so(soffice_main+0x9c)[0xffffb5f66f3c] /usr/lib/libreoffice/program/soffice.bin(+0x8b4)[0xaaaad806e8b4] /lib/aarch64-linux-gnu/libc.so.6(__libc_start_main+0xe8)[0xffffb3d69878] /usr/lib/libreoffice/program/soffice.bin(+0x904)[0xaaaad806e904] ________ As for troubleshooting, I've been following i.e. these instructions for suggestions on how to try fixing the install [from: https://forum.openoffice.org/en/forum/viewtopic.php?f=16&t=53761 ]: 1. Made sure I don't have any existing OpenOffice packages installed (ran 'dpkg -l | grep openoffice'). 2. Deleted the entire configuration directory ("libreoffice/") under "~/.config/". 3. I still can't even run 'libreoffice --help' without getting the same error message as otherwise (although with 'libreoffice --help' it's much shorter): terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException' ________ As of now, these are the packages for LibreOffice that I have installed ('dpkg -l | grep libreoffice'): ii liblibreoffice-java 1:7.0.3-0ubuntu0.20.10.1 all LibreOffice UNO runtime environment -- Java library ii libreoffice 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite (metapackage) rc libreoffice-avmedia-backend-gstreamer 1:7.0.3-0ubuntu0.20.10.1 arm64 transitional package for GStreamer backend for LibreOffice ii libreoffice-base 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- database ii libreoffice-base-core 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- shared library ii libreoffice-base-drivers 1:7.0.3-0ubuntu0.20.10.1 arm64 Database connectivity drivers for LibreOffice ii libreoffice-calc 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- spreadsheet ii libreoffice-common 1:7.0.3-0ubuntu0.20.10.1 all office productivity suite -- arch-independent files ii libreoffice-core 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- arch-dependent files rc libreoffice-dev 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- SDK -- architecture-dependent parts rc libreoffice-dev-common 1:7.0.3-0ubuntu0.20.10.1 all office productivity suite -- SDK -- architecture-independent parts ii libreoffice-draw 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- drawing ii libreoffice-gnome 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- GNOME integration ii libreoffice-gtk3 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- GTK+ 3 integration ii libreoffice-impress 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- presentation ii libreoffice-java-common 1:7.0.3-0ubuntu0.20.10.1 all office productivity suite -- arch-independent Java support files ii libreoffice-math 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- equation editor ii libreoffice-nlpsolver 0.9+LibO7.0.3-0ubuntu0.20.10.1 all "Solver for Nonlinear Programming" extension for LibreOffice rc libreoffice-qt5 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- Qt 5 integration ii libreoffice-report-builder 1:7.0.3-0ubuntu0.20.10.1 all LibreOffice component for building database reports ii libreoffice-report-builder-bin 1:7.0.3-0ubuntu0.20.10.1 arm64 LibreOffice component for building database reports -- libraries ii libreoffice-script-provider-bsh 1:7.0.3-0ubuntu0.20.10.1 all BeanShell script support provider for LibreOffice scripting framework ii libreoffice-script-provider-js 1:7.0.3-0ubuntu0.20.10.1 all JavaScript script support provider for LibreOffice scripting framework ii libreoffice-script-provider-python 1:7.0.3-0ubuntu0.20.10.1 all Python script support provider for LibreOffice scripting framework ii libreoffice-sdbc-firebird 1:7.0.3-0ubuntu0.20.10.1 arm64 Firebird SDBC driver for LibreOffice ii libreoffice-sdbc-mysql 1:7.0.3-0ubuntu0.20.10.1 arm64 MariaDB/MySQL SDBC driver for LibreOffice ii libreoffice-sdbc-postgresql 1:7.0.3-0ubuntu0.20.10.1 arm64 PostgreSQL SDBC driver for LibreOffice ii libreoffice-style-colibre 1:7.0.3-0ubuntu0.20.10.1 all office productivity suite -- colibre symbol style ii libreoffice-style-elementary 1:7.0.3-0ubuntu0.20.10.1 all office productivity suite -- Elementary symbol style rc libreoffice-style-tango 1:7.0.3-0ubuntu0.20.10.1 all transitional package for Tango symbol style ii libreoffice-style-yaru 1:7.0.3-0ubuntu0.20.10.1 all office productivity suite -- Yaru symbol style ii libreoffice-wiki-publisher 1.2.0+LibO7.0.3-0ubuntu0.20.10.1 all LibreOffice extension for working with MediaWiki articles ii libreoffice-writer 1:7.0.3-0ubuntu0.20.10.1 arm64 office productivity suite -- word processor ________ I've found references to this error message online i.e. at: 1. https://bugs.documentfoundation.org/show_bug.cgi?id=84006 ... where the bug report has been closed due to "insufficient data", after lingering around since at least 2014, and affecting i386/amd64 builds as well. 2. Way more in-depth talk on ArchLinux forums on this: https://bbs.archlinux.org/viewtopic.php?id=206869 ("This seems to be a java related error, but I have nothing java related installed.") <= I've tried some of the suggested solutions over there as well, such as setting the environment variable "SAL_USE_VCLPLUGIN=gen". I do have the libgtk2.0 libraries installed, so that doesn't apply as a workaround either -- I've also tried removing libreoffice-related apt packages altogether ('sudo apt-get remove libreoffice*') and reinstalling, that hasn't helped out either. The runtime exception seems to be related to the UNO API, as described in LibreOffice's documentation: https://api.libreoffice.org/docs/idl/ref/RuntimeException_8idl.html All help to resolve this is kindly appreciated!
