using Ubuntu Software Center in 11.10 seems to be impossible to reload. For example, when I go to Software Sources and activate the Universe repo, USC does not automatically reload and so activate the Universe Repo. And I can find no "Reload" button as exists in synaptic. But on a clean install I can't install synaptic because I can't get the Universe repo activated cause I don't know how to get USC to reload.
I wish synaptic was kept in the Main repo.
