hello,
i have also problems with upgrading several apps like ATI-I5, omweather, vnc-viewer, x-chat, ...
i fixed missing pgp keys but the program-manager still complained about missing actual libraries, like libglib2.
i tried to update with apt-get, it fetched the lists but when i try to do an apt-get upgrade, i see that 32 packages are hold back. if i try to install them manually i see lots of missing dependencies.
is there something wrong with the repositories? i used to be able to make upgrades without any errors.

these are my sources:
