Libre office not starting in Debian Buster/Testing

Using Debian testing and uograded a few days ago.
jp@OSUCHSA227:~$ uname -r
4.19.0-5-amd64

Most aps are launching Ok; exceptions VLC and Libreoffice, systems tools in Cinnamon failure seems a know problem.

Repository 1.6.3.0~rc2-1
LO would flash a banner then not open any of its components under Cinnamon or Xfce.
Removed it with Synaptic along with other files connected (e.g. libboost).

Does have java
jp@OSUCHSA227:~$ java -version
openjdk version “11.0.4” 2019-07-16
OpenJDK Runtime Environment (build 11.0.4+11-post-Debian-1)
OpenJDK 64-Bit Server VM (build 11.0.4+11-post-Debian-1, mixed mode, sharing)
Downlaoded the most recent stable, but gdebi opened multiple windows on the group of *debs and failed.

Tried the snap of 6.2.5.2
jp@OSUCHSA227:~$ libreoffice --version
LibreOffice 6.2.5.2 a887734edd14b7c31b8ab527c0422d03c5e16f8b
Icons appear in menus. But, this shows the cycling icon, then also fails to start under Cinnamon, or Xfce from menus (no cycling just fails). Checked permissions and the ones I checked are world executable.
jp@OSUCHSA227:~$ snap find libreoffice
Name Version Publisher Notes Summary
libreoffice 6.2.5.2 canonical✓ - LibreOffice is a powerful office suite including word processing and creation of spreadsheets, slideshows and databases
projectlibre 1.9.1 jibel - Project Management software - alternative to Microsoft Project

So if even the Snap fails, what should I do ?

Thanks.

LibreOffice as Snap | LibreOffice - Free Office Suite - Based on OpenOffice - Compatible with Microsoft was the source of the SNAP
They say "Snaps are fast to install, easy to create, safe to run, and they update automatically and transactionally so the application is always fresh and never broken. "

Thanks for the idea of a flatpack. I will look into it; rather it work than a fresh install.

Apparently you tried the snap from Canonical on Debian, I don’t know if that is even supposed to work and I would not recommend. You could try the Flatpak instead, see LibreOffice in Flatpak format | LibreOffice - Free Office Suite - Based on OpenOffice - Compatible with Microsoft

However, you could also install a regular .deb in parallel, see https://wiki.documentfoundation.org/Installing_in_parallel/Linux

While the snap did not work, the LibreOffice flatpack I downloaded today from their site (Flathub—An app store and build service for Linux) after the simple instructions for using apt to install the flatpack software, did install, be seen by the menu system after reboot, and launched properly.

I hope they get the problem in the repo install/update fixed. I have been spoiled by how well Debian testing has been smooth for years over many update/upgrades.

I do not know how to relay this experience to them. Feel free if you know, or tell me.
