I could install with an error message "unknown media /ALL". It could not run WPS Office.
WPS Office is an office productivity suite, including Writer, Presentation and Spreadsheets. WPS Office is a native snap package in Kubuntu and other Ubuntu flavors. To install it in all currently supported versions of Ubuntu open the terminal and type:
sudo snap install wps-office
The wps-office snap package will be updated automatically when updates are available.
