The installation

$ cd ~/Downloads
# extract

$ sudo dpkg -i *.deb

# optional
$ sudo ln -s /opt/libreoffice6.0/program/soffice /usr/bin/libreoffice

By default, LibreOffice favours nice-looking graphics over speed. If you experience slow graphics, switching off 'Tools - Options - LibreOffice - View - Use Anti-Aliasing' may help.
