I have installed 5.3.4.2 and have now lost all reference to LibreOffice in the main Cinnamon menu. The program is all still there, I can use it by double-clicking on any LibreOffice file. I cannot locate any application files to create menu links manually. Is there any easy way to restore program links to the Cinnamon menu in Linux Mint? Or do I have to uninstall and reinstall?
thanks…
Having used Mint (currently 18) Cinnamon for a while now & having installed many LO versions, I have not experienced this yet.
First go into menu editor and make sure the items are not there or are there and just not checked.
If not there you can add items with the following (Name, Command):
LibreOffice 5.3 libreoffice5.3 %U
LibreOffice 5.3 Base libreoffice5.3 --base %U
LibreOffice 5.3 Calc libreoffice5.3 --calc %U
LibreOffice 5.3 Draw libreoffice5.3 --draw %U
LibreOffice 5.3 Impress libreoffice5.3 --impress %U
LibreOffice 5.3 Math libreoffice5.3 --math %U
LibreOffice 5.3 Writer libreoffice5.3 --writer %U
The icons used are here:

I cannot locate any application files
A view into /usr/bin maybe helpful. You should find an executable shell-script named libreoffice or loffice or soffice (I only work on OpenOffice, so the shell-script is named openoffice4).
The script reads where you find the executable programm part (in my case it reads “exec /opt/openoffice4/program/soffice “$@””). Should be similar to LibreOffice. From there you may create links for starting the different applications…
That is great thanks, I have restored the Libre Office links to my menu system. Not sure if this is a Libre Office glitch or something to do with Mint or Cinnamon. Interestingly Terminal claims that Libre Office is not installed on my computer!

The program ‘libreoffice’ is currently not installed. You can install it by typing:
