I've just install wine in my Xubuntu 18.10 with the command "sudo apt install wine" but there's no shortcut in my menu.
I checked the /usr/share/applications, there's nothing there too.
Is there a way to generate that file. Try to uninstall/reinstall it with the softwares application or via synaptic but with no more success.
As I use Ubuntu/Xubuntu for 11 years, I found an alternative way to launch sketchup without anything in my menu but I think it should be fixed for the beginners.
Edit: The answer is not only to make a launcher. But the apt install program didn't create anything in the menu. I don't have neither the right clic option "open with wine..". I would like to have an integration of wine as usually in Xubuntu. It doesn't work for the 18..10 version.
