Synaptic Package Manager does not work after upgrade to Ubuntu 11.04

[drakejacob]

I have recently upgraded to Ubuntu 11.04 from Ubuntu 10.10. After the upgrade, I wanted to do a system cleanup using Synaptic Package Manager. After, I have marked a package for removal, the "Apply" button is still shaded, i.e., I am not able to click the "Apply" button. The "Apply" button is still not functional even I am able to download and install packages. Can anyone tell me what is going on?

have you clicked on the reload button?


Sorry for the late reply, but I have clicked on the "Reload" button and then clicked a package for removal. The same thing happens, the "Apply" button is still shaded.
