Today, you can test or use LibreOffice in your Gnu/Linux distribution
without the need of going through the installation process. How? With AppImage, a format for distributing portable software on Linux without the need of superuser permissions to install the application.
Do you want to try?
Download the file, make it executable by flagging the option in the “Properties” panel (to access it, right-click on the icon), and enjoy the application! No need to install the software. No system libraries or system preferences altered in the process.
The versions of LibreOffice you can download are 64-bit ones, in some language. If you want the 32-bit version or another language please contact me antonio.faccioli [at] libreoffice [dot] org.
