The last time I worked in Elementary OS, GKSU could be installed. However I see it no longer has an install candidate. Is there way I can get Xampp runner to launch, without having to invoke a terminal window to input the password (It requires permissions to run).

Functionally it works, but really breaks the experience. So many app make use of the system GUI to input the password if they need running, however without GKSU I cant seem to get this right. The bellow article has the original reference

Add custom launcher

    Does pkexec work instead of gksu? It should already be installed. May 15, 2019 at 10:55
  • Thanks for the advice, I entered te following as a run option: pkexec /opt/lampp/manager-linux-x64.run Now that did not ask for a password it did not run the application either. Some more research says to rather make use of pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY /opt/lampp/manager-linux-x64.run While that works in the terminal, it does not work in the app launcher May 16, 2019 at 11:20

Same here. Removing gksudo and gksu totally sucks if there is no consistent replacement. I tried every manual on the net. For ubuntu pkexec works, since they are in nautilus, but in elementary juno we are SCR3WED...

Where in other distributions people are succesful, for elementary os juno NOT ANY forum idea to launch XAMPP via a desktop file will work.

The location of the desktop file: ~/.local/share/applications/file.desktop

I tried:

[Desktop Entry]


Name=XAMPP Control Panel

Comment=Start and Stop XAMPP

Exec=pkexec /opt/lampp/manager-linux-x64.run





update the desktop files by:

sudo apt-get update -y

No results, so I started going trough ubuntu forums, trying alternatives. Taking very much time. In total, my attempts for the Exec= line:

gksu /opt/lampp/manager-linux-x64.run
sudo -c bash '/opt/lampp/manager-linux-x64.run'
pkexec /opt/lampp/manager-linux-x64.run

None of these work in juno! I spend 2 hours debugging my .desktop file, in the end I found a good soul that posted this command at a forum:

grep '^Exec' file.desktop | tail -1 | sed 's/^Exec=//' | sed 's/%.//' | sed 's/^"//g' | sed 's/" *$//g'

Running this you can run file.desktop via terminal so at least you can see what happens. It gives all errors your script will go trough in the terminal, so at least you are a step further. But what really happens: Nothing!... To find you script is ok, but elementary support is crap. Ubuntu cuts out gksu, Debian daughter distribution developers are depending on it, there is no solution for practical consequenses and the user is SCR3WED.

Is that what linux is all about. The poster of this question asked his question 4 months ago, and there is no solution yet for an common used application like XAMPP.

Comon guys.

This way people are forced to attempt to force-install gksudo packages from an older kernel in this new architecture o.s. Which is asking for other problems, but users need a solution so who can blame them.


Because I am crazy I tried it. Install gksudo.


wget http://archive.ubuntu.com/ubuntu/pool/main/libg/libgtop2/libgtop-2.0-10_2.32.0-1_amd64.deb

sudo dpkg -i libgtop-2.0-10_2.32.0-1_amd64.deb


wget http://archive.ubuntu.com/ubuntu/pool/universe/libg/libgksu/libgksu2-0_2.0.13~pre1-6ubuntu8_amd64.deb

sudo dpkg -i libgksu2-0_2.0.13~pre1-6ubuntu8_amd64.deb

sudo apt -f install -y

(needs: sudo apt -f install -y to fix dependencies)


wget http://archive.ubuntu.com/ubuntu/pool/universe/g/gksu/gksu_2.0.2-9ubuntu1_amd64.deb

sudo dpkg -i gksu_2.0.2-9ubuntu1_amd64.deb

Tried to config my file.desktop Exec= line again to gksudo and gksu. It simply doesn't work. A terminal icon comes up in the pantheon taskbar (panel) and hangs for 10 seconds and disappears again. Same result. But when I tried the debug command again:

( in ~/.local/share/applications/file.desktop )

grep '^Exec' file.desktop | tail -1 | sed 's/^Exec=//' | sed 's/%.//' | sed 's/^"//g' | sed 's/" *$//g'

It DID open the gksudo command prompt! Why, I don't now. This is the most frustrating one of all. It is a great thing John Mcenroe isn't a elementary OS juno user.
