I have just installed Mint 14 and have been informed I have a large number of updates available. In the past, after clicking the tray icon I am shown the update screen, clciked OK and the download and updates are installed. However, in this case, absolutely nothing happens. I've tried uisng KGET with the same result - nothing happens - no screen with kget appears and no hard drive activity or sign of downloading. What have I done incorrectly, please? I have a good Internet connection which is accessed OK for email and browsing.
