Comment 74 for bug 192992

I resolved with ifoo's package:

http://launchpadlibrarian.net/12080601/packages.tar.bz2

But before i have cleaned cache (sudo apt-get clean cache)

After i've decompressed the packages.tar.bz2 in my desktop and installed the contents (with a simple double click of the mouse) in this order:

update-manager-core_1%3a0.87.8_i386.deb
update-manager_1%3a0.87.8_all.deb
python-apt_0.7.4ubuntu5_i386.deb

Initially i've a broked file (update-manager, maybe for error in sequence of installation), but with command "sudo synaptic" and with the filter "broke" i've disinstalled this error file package. After the "cleaning" i've installed the above three package of Ifoo without problems... ;)
