Description of problem: running live-cd the polkit authentication dialog doesn't pop-up when launching yumex so it doesn't work.
Version-Release number of selected component (if applicable): F18 RC3-Alpha Xfce spin, yumex 3.0.6
How reproducible: always here, but my system is very old with 1GB memory and although I'm careful with the testing I see that these F18 early spins really overload it so I don't know if it influences or not.
Steps to Reproduce: see description.
Actual results: see description.
Expected results: polkit authentication dialog should pop-up or as there's no root password on live-cd then yumex maybe should work right away.
Does it silently fail, or...?
This is how yumex works in a F17 installation:
On the live-Cd, since there's no password for root, yumex is stuck on that screen but *without the authentication box*.
yumex is there waiting so I think it's some polkit issue that in the live environment should allow yumex without asking for password (maybe, I don't understand about this).
It looks like you are hit by this one
if the liveuser is not member of the wheel group, then polkit don't work and is hanging.
usermod -G liveuser,wheel liveuser
should make it work
Just confirming that that makes it work.
