LibreOffice 7.1.7 is available for anyone on the workstation or server-gui channels. It will automatically be updated when autoupdate is run. This is a major version update. You can manually upgrade using the autoupdate utility.
Libreoffice 7.2 is currently automatically installed using the GUI installation tool from the jcchome-menu.
To manually install this version, you can also run the following:
sudo apt remove libreoffice7.2* libobasis7.2* -y
sudo apt install libreoffice7.1* libobasis7.1-* -yYou will need sudo or root access. Run the first line if you already have LibreOffice 7.2 installed and want to change to the stable channel.
