Erm, huh. Well, osso-software-version-unlocked is a package rm_you put together to install the correct osso-software-version-rx*4-unlocked package. Code: apt-get remove osso-software-version-unlocked Then try installing the osso-software-version-rx44 again. Also do: Code: cat /etc/apt/sources.list.d/hildon-application-manager.list and post its output here.
apt-get remove osso-software-version-unlocked
cat /etc/apt/sources.list.d/hildon-application-manager.list
