根据这个：

对于 10.04 及以上版本，您需要执行此操作来安装 DeskJet 3762 的打印机支持
sudo apt-get install --assume-yes libcups2 cups libcups2-dev cups-bsd cups-client libcupsimage2-dev libdbus-1-dev build-essential ghostscript openssl libjpeg62-dev libsnmp-dev libtool libusb-1.0-0-dev wget python-imaging policykit-1 policykit-1-gnome python-qt4 python-qt4-dbus python-dbus python-gobject python-dev python-notify python python-reportlab libsane libsane-dev sane-utils xsane
但是，这会失败：
Package python-imaging is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
python-pil
E: Package 'python-imaging' has no installation candidate
E: Unable to locate package python-qt4
E: Unable to locate package python-qt4-dbus
E: Package 'python-dbus' has no installation candidate
E: Unable to locate package python-gobject
E: Unable to locate package python-notify
E: Unable to locate package python-reportlab
有什么建议么？
