Hello again @testware73

I was informed that this guide is outdated and also that original project is maintained by community.
https://aur.archlinux.org/packages/onlyoffice-bin

With manual installation you can try adding dependencies and running the whole project again:

sudo pacman -S --needed base-devel git

git clone https://aur.archlinux.org/onlyoffice-bin.git

cd onlyoffice-bin/

// Add dependencies
sudo pacman -Syy gst-plugins-ugly gst-plugins-base-libs gst-plugins-bad-libs gst-plugins-base gst-plugins-good

makepkg -si

Please note that is by no means an official recommendation.
