Dependency issue - what to do??

Hi there I'm hoping someone may be able to offer some help with a dependency issue. I've been trying to install a .deb file so I can use my Huawei e220 which is a usb 3G modem for use with vodafone. The 56k dial-up is driving me crazy! There were several python dependency issues with the .deb file. This is the first time I've really had to install anything extra in 64studio (linux in fact!) and having read a bit I was able to get most dependencies going except the following- $ sudo dpkg -i vodafone-mobile-connect_svn20090324_all.deb (Reading database ... 107220 files and directories currently installed.) Preparing to replace vodafone-mobile-connect 2.00.00-1 (using vodafone-mobile-connect_svn20090324_all.deb) ... Unpacking replacement vodafone-mobile-connect ... dpkg: dependency problems prevent configuration of vodafone-mobile-connect: vodafone-mobile-connect depends on python-gobject; however: Package python-gobject is not installed. dpkg: error processing vodafone-mobile-connect (--install): dependency problems - leaving unconfigured Errors were encountered while processing: vodafone-mobile-connect $ So I connected to debian packages via the link in Iceweasel and downloaded python-gobject and attempted to install as follows- $ sudo dpkg -i python-gobject_2.14.2-1_amd64.deb dpkg: regarding python-gobject_2.14.2-1_amd64.deb containing python-gobject: python-gobject conflicts with python-gtk2 (<< 2.10) python-gtk2 (version 2.8.6-8) is installed. dpkg: error processing python-gobject_2.14.2-1_amd64.deb (--install): conflicting packages - not installing python-gobject Errors were encountered while processing: python-gobject_2.14.2-1_amd64.deb $ So I'm not quite sure what to do next?? Any advice would be most welcome!! Cheers, thanks for any help. Rich
