Hi there!
If anyone want to install WPS Office in Portuguese. I put in my repository the complete suite. Interface, dictionary, templates and extras fonts. I’ve tested in Lubuntu bionic and focal and worked well.
Its easy to install, just use those commands:
wget -qO - "https://winunix.github.io/debian/public.key" | sudo apt-key add -
echo "deb https://winunix.github.io/debian focal main" | sudo tee /etc/apt/sources.list.d/winunix-focal.list
sudo apt update
sudo apt install fonts-3rd-party
sudo apt install wps-office-full
