If we install Xfce from the sources or even through the repository for the first time, it is possible that when trying to open the menu we will find this error:
The solution to this problem is very simple. If we have a terminal installed we open it and see if the folder exists menus within / etc / xdg /. With ls should serve:
$ ls -l /etc/xdg/
If it is not, we create it:
$ sudo mkdir /etc/xdg/menus
and then we create a file called xfce-applications.menu:
$ sudo nano /etc/xdg/menus/xfce-applications.menu
and inside we hit this content. We can automatically access the menu.
