I download Mike Walsh' portable LibreOffice 6.0.0.3 and downloaded deb-packets from LibreOffice site to this version to add Russian interface language.
They contain opt folders. I copied them to /opt, but no have no Russian language.
How can I add language packs to portable program?
Thank you!
@Zedward :-
I tend to download and use the English-only AppImage. I was going to suggest that you download the same release version - it's stable, and has been around for ages - in the full, multi-language support version.....but it appears that LibreOffice have decided to cut off access to ALL their older AppImages.
All you can access now is v7.2 or newer.....and unfortunately, these days LibreOffice only comes in 64-bit format, I'm afraid.
I guess I could build you a Russian-language version of v6.0.0.3 using Fred's AppImage build-scripts - you can still access older builds in standard formats like .deb, .rpm, etc., along with the lang_packs - but you'll have to wait a couple or three days. I can't do it till after the weekend. I may disagree with what Mr. Putin is doing, but I have nothing against the Russian people themselves!
This 32-bit AppImage of v6.0.0.3 you've got in the 'portable' was a "special" I built using the afore-mentioned scripts. It was never supplied by LibreOffice themselves like this, because they ONLY package 64-bit AppImages.
Leave it with me. I'll see what I can do.....but please be patient. I DO have a life outside these forums!
Mike. 
Tnak you very much! It will be great!
