unable to update files
hi, whenever I do an ugrade or something with apt, it keeps telling me that these are held back, i.e. not upgraded:
bittorrent-gui contact-lookup-applet libedata-book1.2-2 libpt-plugins-alsa libpt-plugins-v4l2 xfce4-mixer
how can I upgrade them or if they are newest version, how do I tell my ubuntu?
