Untrusted application launcher

[Norm24]

Enter directory: from Places-Computer-File system

/usr/share/app-install/desktop

Find and right-click on "LibreOffice" file, choose "Copy to the desktop".

Did that already and get this error message:

Details: Failed to execute child process "libreoffice" (No such file or directory)

List the permissions to show us. From the directory the file is in.

ls -l <file>

Nevermind

You can use sudo to change the permissions.

sudo chmod +x <file>

Can you post the contents of the file here in code tags?

It looks like the file you copied from `/usr/share/app-install/desktop' tries to execute libreoffice as the launch command, but you have LO-4.0 right? I think you need the command to be libreoffice4.0 to launch the program. If the file worked except the bad command, you could get the file from /usr/share/app-install/desktop and edit it to launch libreofffice4.0.

Root owns the file.

I didn't create it I dragged it from the applications menu.It launches from the application menu no problem.If I drag it to the panel it launches no problem.It simply won't launch from the desktop,for some reason this shortcut is locked when on the desktop.

Yes your right, I just tried in gnome classic and the file is owned by root.
Same in unity just for the libreoffice dash entry.
I think it may be because the .desktop file for libreoffice in /usr/share/applications actually links to
/usr/lib/libreoffice/share/xdg/startcenter.desktop

So I'm not sure how all that works.

Can you drag other applications from the menu to the desktop and make executable?

Editing the command to libreoffice4.0 did the trick.

At first I didn't believe it, but then I tried it for myself, I can't believe Ubuntu makes it so difficult to add icons to the desktop :/

Seems like some applications will work and launch successfully like jEdit, I am able to add to the desktop and launch, but others like Libre Office fails. This is _almost_ unbelivable.

All the more reason for you to use (by force) unity launcher.

Not trying to get political here but since Gnome3 the paradigm of what the desktop is and what it is supposed to be has changed.
Nautilus' control of the desktop is going away, and there is an effort to move users away from using the desktop as a catchall for files, folders, launchers etc.
I'm not sure how it is all going to wash out, but how people are "expected" to use their systems is changing drastically.
I neither endorse or condemn. I'm along for the ride and try to adapt.
So don't expect the use of the desktop in the old manner to be accommodated easily.

My 2 cents

Yep, that's what I mainly use, well that and the dash.

Nevermind.Saw this is solved already.

Step 1-Right click program. Open and open properties.
Step 2-Under "Permissions" tab,look for "Execute:"
Step 3-Place a check mark in the box,next to "Allow executing file as a program".

Program should now launch. Had the same problem after creating desktop icons,as soon as I did that the programs launched and worked.
