Ubuntu – How to uninstall WPS Office for Linux

OK so...

32-bit (depending on your hardware - check by uname -a):

cd && wget -O wps-office.deb http://kdl.cc.ksosoft.com/wps-community/download/a21/wps-office_10.1.0.5672~a21_i386.deb
sudo dpkg -i wps-office.deb
sudo apt-get -f install && rm wps-office.deb
wget -O web-office-fonts.deb http://kdl.cc.ksosoft.com/wps-community/download/a15/wps-office-fonts_1.0_all.deb
sudo dpkg -i web-office-fonts.deb

For 64-bit:

cd && wget -O wps-office.deb http://kdl1.cache.wps.com/ksodl/download/linux/a21//wps-office_10.1.0.5707~a21_amd64.deb
sudo dpkg -i wps-office.deb
sudo apt-get -f install && rm wps-office.deb
wget -O web-office-fonts.deb http://kdl.cc.ksosoft.com/wps-community/download/fonts/wps-office-fonts_1.0_all.deb
sudo dpkg -i web-office-fonts.deb

And that's it.

Edit: As the wget links are likely to break at every version change, you can also visit the download page here as noted by JonasCZ in this comment

As an addendum to Roel Brook's answer, I found that you can actually change this setting in the binary file. To do this open terminal and enter

sudo $EDITOR `where et`

Then look for:

${gInstallPath}/office6/${gApp} -style gtk+ ${gOptExt} ${gOpt} "$@"

and change it to:

${gInstallPath}/office6/${gApp} -style motif ${gOptExt} ${gOpt} "$@"

Then save and close. Now the changes will be persistent.
