I have used LibreOffice for many years. I have never had a problem installing until version 6.4 on a Debian 10 machine with Kernel 184.108.40.206. When I install, using sudo the applications install fine, but when I go to execute them, they fail to start. The owner and group of the executable's is root - root. I uninstalled them and attempted to install them without using sudo and get a permissions error if sudo isn't used. This is a recent update to Debian, and I do have 6.3 running on other systems successfully. This is the first time I have tried to install 6.4 from the x86_64 download new.
Steps to Reproduce:
1.Download current release to standard download folder and extract.
2.change to folder containing extracted debs.
3.run "sudo dpkg -i *.deb
4.Execute any program from menu.
Programs install. Uninstalled and reinstalled without sudo, install will not begin without root permission to execute installers and create folders for programs.
Programs installed, proper menu icons were created under office menu. Programs just fail to start.
User Profile Reset: No
OpenGL enabled: Yes
Programs should execute if installation instructions are followed properly.
Rene: thought you might be interested in this one since it concerns Debian.
(Usually I advise using LO packages from distrib repository)
https://packages.debian.org/buster-backports/libreoffice exists on Debian 10. (and yes, works of course.)
