F1 opens your system's default HTML viewer (typically, a browser), with either online, or locally installed, help. What application opens in your case?

(and JavaScript needs to be enabled for the help to work, btw)

Thanks for reply.

Upon pressing F1, "text editor" opens, displaying the text noted above. 

Many packages are installed relating to java, such as: java-common, javascript-common, ure-java, libunoloader-java, etc. 

What specifically must I know and invoke for java?

Thanks for reply. Appreciated. Using synaptic, I found the xdg files and re-installed them. 

Now, when I press F1, the script text shown above no longer appears and the browser comes up with an message stating a certain file is not found.

Pressing F1 or Help links to the default browser (could be either Firefox or Chromium) and a page shows with message to the effect no help files found.

The problem is the lack of system integration. Seems LO, FF, Chrome are now 'snap' installs. 

The problem is solved by installing a new browser from the deb repository. I found 'slimjet', and this works perfectly to show the help files.

This help problem is only one of many LO bugs I have discovered. The worst is severe input lag, causing LO to be entirely useless.

LO is no longer the capable, friendly suite is was once upon a time.

Described is most common situation in new Ubuntu, snap browser and regular LO.

There's more. If both browser and LO and snap (like in minimal install and LO added later), F1 opens local help. Maybe because snap installs it.

If it's a Snap issue, the primary feedback channel should be Ubuntu's bug tracker: https://bugs.launchpad.net/ubuntu/+source/libreoffice/

Comment 16 Stéphane Guillou (stragu) 2024-03-08 01:35:03 UTC
I ran into this after upgrading to Ubuntu 22.04 + GNOME 42.9, with own build of help submodule or installed help pack from.deb, opening in Chromium or Firefox (both snaps).

With Firefox, I get the following message in terminal:

Gtk-Message: 01:59:45.957: Not loading module “atk-bridge”: The functionality is provided by GTK natively. Please try to not load it.

And the page fails to load with:

   File not found
   Firefox can’t find the file at /tmp/lu9130c8gp.tmp/NewHelp3.html.

(that last number gets incremented every time I attempt to open the help)

With Chromium as the default browser, I get this in terminal:

   (chrome:11153): Gtk-WARNING **: 10:59:31.519: GTK+ module /snap/chromium/2768/gnome-platform/usr/lib/gtk-2.0/modules/libcanberra-gtk-module.so cannot be loaded.
   GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported.
   Gtk-Message: 10:59:31.519: Failed to load module "canberra-gtk-module"
   [11153:11153:0308/105931.558514:ERROR:policy_logger.cc(157)] :components/enterprise/browser/controller/chrome_browser_cloud_management_controller.cc(161) Cloud management controller initialization aborted as CBCM is not enabled. Please use the `--enable-chrome-browser-cloud-management` command line flag to enable it if you are not using the official Google Chrome build.

And Chromium throws an ERR_FILE_NOT_FOUND on the same tmp file.

I installed Falkon as a .deb from the Ubuntu repos, no problem opening the help files with that as a default.
