Problem creating Desktop shortcuts through Debian dpkg installer scripts

Hi,

I am creating a debian package (*.deb) for my application using the command

Quote:

fakeroot dpkg-deb --build <mypackage>

I am using debian pre/post installer scripts to do certain tasks before/after installation/uninstallation. One such task is to create a shortcut on the user's desktop to launch my application. I am trying to do this by copying the *.desktop file from /usr/share/applications/<mypackage>.desktop to "${HOME}"/Desktop. As we are running the dpkg install command (or gdebi-gtk UI installer) as root (sudo) unfortunately the process does not predicate the user on whom behalf the install command is running. Hence the copy is not taking place as expected. The script could not figure out the correct user if I issue the command "logname", "id -un", "whoami" or "$USER" as all these commands return the user as root. I also tried to create a symbolic link on the users Desktop directory and failed to do that.

Please help me how to solve this problem?

Also, I am using delivering a notification through a pop-up screen if the user tries to remove/uninstall on his system that installed package when one of the instance is running. This I am doing using "notify-send" command of "libnotify-bin" package. To get the pop up screen I need to run the command as

Quote:

gksudo -u <user> "sudo dpkg --purge <mypackage>"

What my question is, since we are running this using gksudo, why I need to give sudo command once again and why I am getting "dpkg: requested operation requires superuser privilege" error if I am not giving that?

dh_builddeb

DH_BUILDDEB(1)							     Debhelper							    DH_BUILDDEB(1)

NAME

       dh_builddeb - build Debian binary packages

SYNOPSIS

       dh_builddeb [debhelperoptions] [--destdir=directory] [--filename=name] [--params]

DESCRIPTION

       dh_builddeb simply calls dpkg-deb(1) to build a Debian package or packages.  It will also build dbgsym packages when dh_strip(1) and
       dh_gencontrol(1) have prepared them.

       It supports building multiple binary packages in parallel, when enabled by DEB_BUILD_OPTIONS.

       When the Rules-Requires-Root field is not (effectively) binary-targets, dh_builddeb will pass --root-owner-group to dpkg-deb(1).

OPTIONS

       --destdir=directory
	   Use this if you want the generated .deb files to be put in a directory other than the default of "..".

       --filename=name
	   Use this if you want to force the generated .deb file to have a particular file name. Does not work well if more than one .deb is
	   generated!

       -- params
	   Pass params to dpkg-deb(1) when it is used to build the package.

       -uparams
	   This is another way to pass params to dpkg-deb(1).  It is deprecated; use -- instead.
