I have Debian (11) BullsEye and Libre Office 7.0.4.2 the standard repsitory, does not have Libre Office 7.3 what repository do I need to install 7.3?
If you are not familiar with your Linux system, you better stick to the version of your repository. I still use LO 6.0 (Ubuntu 18.4) for my daily work and LO 7.3 for testing and support.
