Bug 157764

Description:
After confirming
"libreoffice-help-en-us is already the newest version (4:7.5.6-0ubuntu0.23.04.1)." 
And dependencies are present and correct
	libreoffice-common 		>= 1:6.1.0~
	libreoffice-help-common 	= 4:7.5.6-0ubuntu0.23.04.1
Help > LibreOffice Help Or press [F1] returns an Error pop-up stating that the above are not installed.
There are times I need the LibreOffice help when I do not have access to the internet
I have followed directions for installation of help from several sites including
https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1869561
and 
https://wiki.documentfoundation.org/Documentation/Install/Linux#Installation_of_LibreOffice_on_GNU.2FLinux_systems
and continue to not have had a functional off-line help for months

I am unsure whether the component should be installation or LibreOffice however I am selecting the latter



Steps to Reproduce:
1. sudo apt-get update
2. sudo apt-get install libreoffice-help-en-us
        "libreoffice-help-en-us is already the newest version  
           (4:7.5.6-0ubuntu0.23.04.1)." 
3. In Synaptic Package Manager confirm dependencies are present and correct.
    Referance 
	libreoffice-common 		>= 1:6.1.0~
	libreoffice-help-common 	= 4:7.5.6-0ubuntu0.23.04.1
     [Reference: https://ubuntu.pkgs.org/23.04/ubuntu-updates-main-amd64/libreoffice-help-en-us_7.5.6-0ubuntu0.23.04.1_all.deb.html]

 In LibreOffice
4.  Click on Help > LibreOffice Help Or press [F1] 

Finding the HTML help files do exist
1.  Paste "/usr/share/libreoffice/help/en-US/text/swriter/00/00000004.html"
in LibreWolf browser [Both Firefox and Chrome report it as "file not found"] 
Which becomes "file:///run/user/1000/doc/637ad053/00000004.html"
and see the HTML text shown in "Other Information" below

This should show that the HTML help files do exist in /usr/share/libreoffice/help/en-US/text/

However the help or index.HTML files are strange
/usr/share/libreoffice/help/help.html     1.4 KiB [most other pages  ]
/usr/share/libreoffice/help/index.html    3.9 KiB [are 5KiB or higher]
which when I click on the latter shows up in Firefox with this address
file:///run/user/1000/doc/d883326b/latest/index.html
and reports the file cannot be found.
When opened in LibreWolf, it is a blank screen.



Actual Results:
Receive the following pop-up
"built-in help for current UI language (English(USA)) is not installed on your computer"   [read on-line] [cancel]

Expected Results:
That Firefox opens with the index page or table of contents found in,
/usr/share/libreoffice/help/en-US/text/
in opening possibly one of these files.
/usr/share/libreoffice/help/help.html
/usr/share/libreoffice/help/index.html



Reproducible: Always


User Profile Reset: Yes
