Libre Write Send / Document not attachment created in Thunderbird

I wonder for who it does work. and what they did to get it work

For me on Ubuntu.

i don´t care about ubuntu I do care about Sending Documents as Email

And so - WHAT ARE YOU TRYING TO TELL HERE NOW? Are you a troll, after all that has been said above?

For me on all Windows/Linux systems where I installed LibreOffice so far. I avoid container packages, though.

I join your assessment. (If you stop calling me troll )

What about fedora?

It seems obvious at this point, that you found a bug there, with some specific configuration (and maybe even on many / most current configurations - I have no idea, since I don’t use it). You filed a bug report (as you are possibly aware). Now it’s time for others to look at this bug, try to reproduce, find out how to reproduce (i.e., if there is some specifics, like the suspected container involvement, or maybe something else), and then hopefully fix it.

Did I answer your “What about fedora?” question?

One thought. Does having libreoffice directly access a running email program, potentially expose libreoffice to external hacking?

I ask this because it does not happen when the email porogram is used alone to attach saved documents.

What makes you think LibreOffice accesses a running email program “directly” (and what that “directly” means)? Because, as I explained elsewhere, “it” may well happen, when the document created by LibreOffice for the attachment is inaccessible by an email program, which definitely doesn’t require any direct access, only using paths in different containers.

I would also avoid containers, unfortunately the 24.x for linux-arm64 is currently only available via flatpak!

The classic debian package for linux-arm64 is actually 7.4.7.2

You could always contribute to development of LibreOffice to fix the issue if it doesn’t meet your standards. It is community developed so participation is encouraged.

Works for me out of the box since 22 years with 4 or 5 different distributions, Thunderbird, StarOffice, OpenOffice.org, Apache Openoffice and LibreOffice.

We had situations in the past where LO worked with one mail client and did not work with Thunderbird.
The system programmer analyzed the system logs and found out that there was a problem with the AppArmor rules.

Good to know.

This feature (File>Send attachment) requires some kind of communication between different applications that are bundled by the maintainers of your desktop environment. It is their promise, to take care that the entire desktop environment is well integrated, despite the fact that applications come from different maintainers, namely The Document Foundation and Mozilla Foundation.
Personally, I would not bother at all about this minor convenience feature. I do save my documents, and I can attach any file types to emails using any application running on desktop or in a browser.
Nevertheless, it is a bug. I’d suspect that the failure is on the distributor’s side.

How do you see the Apparmor rules? I had a look at the Apparmor website and couldn’t understand it?

Maybe this documentation will be useful.
If you have any specific questions, I’ll invite our Linux specialist and we’ll try to figure it out together.

Both LibreOffice senddoc and Thunderbird are in “Enforced” mode while Evolution is in “Unconfined” mode. Could this be why sending a doc to email works with Evolution but not with TBird?

Yes, it is quite possible.
Try disabling the AppArmor and see if that solves the problem.
