I'm using Lubuntu 20.04, (almost) freshly installed.
I've succesfully created few .desktop entries in ~/.local/share/applications/ for wine applications. However, there is one wine app which I would like to prevent from connecting to the internet. So I used an approach with no-internet group.
From .desktop entry, wine "~/.wine/drive_c/Program\ Files/Folder/executable" works well.
From terminal, sg no-internet wine "~/.wine/drive_c/Program\ Files/Folder/executable" works well. From terminal, gtk-launch appname.desktop containing the latter command in Exec works well. But from menu it does not launch: no errors, no messages, nothing. I also tried sg no-internet -c 'wine "~/.wine/drive_c/Program\ Files/Folder/executable"' and creating a .sh script, but the former does not even launch with gtk-launch with error no application appname, the latter also fails with sh: 0: could not open appname-launcher.sh.
How does one configure a .desktop file to launch something with sg? Why does gtk-launch launchs command and menu entry not?
The appname.desktop has permissions 777 (just in case).
