How to install Libre Office help file in Linux Mint?

I am using Libre Office 7.5.;22 (X86_64) on my computer running Linux Mint 21.1. After a long struggle I managed that upgrade. However, in my Software Manager, I tried to download the file - libreoffice-help-en-us - but it does not install into Libre Office.So on the web site I downloaded the file - LibreOffice_7.4.6_Linux_x86-64_rpm_helppack_en-US.tar.gz - and there’s no instructions on this site about how the heck I install it into my Libre Office installation. Perhaps I’m dumb, but where are the instructions for installtion? Thanks.

IMHO Mint is using apt, so you will need a debian-package .deb
.
rpm is for RedHat package manager and used in other distributions…

Start here:

Additional hints: Versions of LibreOffice and help must match exactly. Help is not integrated to LibreOffice, it will be still opened in browser, but the files are local then.

Is Mint now already that broken that it doesn’t distribute a helppack that actually corresponds to and complements the distributed program package? I can’t imagine. Whatever “it does not install into Libre Office” might actually mean. Note also that installing a 7.4.6 helppack (regardless of package format) along with a LibreOffice 7.5.2 installation may not work, and whether shoving a TDF build helppack (even if it was of a matching release) into a distribution’s installation would actually work at all is doubtable.

try:

> sudo apt-get update
> sudo apt-get install libreoffice-help-en-us

True, the apt should install the deb files. But the release is 7.3, not 7.5. 7.5 has significant improvements. The flatpak release is 7.5, but has no help files: help defaults to a web page. Seems LO is no longer suporting local offline help function, instead supporting the online help. I suppose this online method ensures all users have the latest edition of help.

It seems that there are help installation packages for as recent as 7.6.0.1 - Index of /libreoffice/old/7.6.0.1/rpm/x86_64. Perhaps it is the third party packagers who do not include the help packages?

PRE-release 7.6 is available from LO website, not the repos; and it is a deb.tar file, not flatpak. Caveat emptor: a pre-release will have bugs.

Nonsense, but the parts have to fit together. The first question here was mixing rpm vs apt. You now have problems of apt not updating flatpacks. All quite expectable and no valid base for the false conclusion I cited above.

You have to decide yourself. Some distributions will not do “mayor” updates to software in an release, so lagging behind. Some try to reduce the work to integrate by using snap/flatpack, but you add friction when it comes to macros interacting with shell, calling browsers to show local help. Or you can add additional repository for software, where you think it is necessary to use newer versions. Without repository you may install and maintain downloads yourself.

Freedom and choice may result in additional work, but I will not advocate to reduce choice…

Flatpak has no LO help files, so LO does not support flatpak to the same extent as deb. If you find LO 7.5 Help in flatpak, please let me know. Thanks.
