Hi all,

I've installed F15 Gnome 3 and after a while in using this interface, I decided I rather go back to the LXDE desktop. so I've removed GNOME and installed LXDE.

I'm not sure if it worked in GNOME 3 - but now in the LXDE I'm unable to install software using Add/Remove Software applet or check for software updates.

When I attempt to do so - I get an error message telling me that "Authorization failed" - it doesn't even prompt me for the root password and I've resorted to having to do the install of new software and updates through the command line using su and then issue the commands "yum install ..... " and "yum upgrade".

Does anyone know how to resolve this issue?

thanks

you can do this as root in cli to update:

yum update

to install/remove,

yum install packagename
yum remove packagename

if synaptic is available, you could install it:

yum install synaptic

then, as root, run synaptic.

or press alt+F2 and type gksu synaptic

I installed from the F15 LXDE spin live CD, so YMMV. My first thought is that you may be missing polkit and/or lxpolkit. I use yumex if I want a gui, or yum from an lxterminal window to do my updates. The only problems I've encountered are due to my misconfiguring the repositories. I don't use PackageKit (I find it even slower than yumex), so I can't comment on it. I often use synaptic for deleting unwanted packages, but haven't tried using it for updating in quite a while.
