Update Problems

After upgraded to 12.04 a few package got into some problems and everytime I try to update and upgrade I kee running into the same problems.
The error message I get is:

E: firefox: subprocess installed post-installation script returned error exit status 2
E: firefox-branding: dependency problems - leaving unconfigured
E: firefox-globalmenu: dependency problems - leaving unconfigured
E: firefox-gnome-support: dependency problems - leaving unconfigured
E: konqueror: dependency problems - leaving unconfigured
E: samba-common-bin: subprocess installed post-installation script returned error exit status 2
E: nautilus-share: dependency problems - leaving unconfigured

And within synaptic trying to fix the broken packages doesn`t seem to help, coz the problem remains.
How to resolve without immediately losing all of my personal details in firefox and such.

Cheers,
Dave
