Unmet dependencies

[oglipogli2]

I'd likely just download those 2 packages & try installing with dpkg but first you could try -
Can you install aptitude? and if so what does it report?

sudo apt-get install aptitude

if that works then

sudo aptitude upgrade

If it fails then choose no (n) & post complete output

Nothing you've posted indicates - run some commands & check - http://www.tecmint.com/how-to-check-...pace-in-linux/

Have seen some rare examples in launchpad of this behavior, though no explained reason??

There must be a conflict in the PPA. If I remember correctly I received similar errors after adding a PPA.

What I did to solve that was to first uninstall the program, unticked all the sources and just left the PPA of the program I needed. Then I installed. I got the latest version of what I needed, and lost those errors.

I also unticked the programs PPA's after and ticked back the main ones.
