this is an issue I have googled a lot and I have tried a lot of fixes, but non of them really worked.

At some point (I can't remember when/how) my Update system sort of broke, and since then it is always complaining about "Not all updates can be installed, run a Partial Upgrade".

If I click on Partial Upgrade, I get the following result

But running apt-get install -f does not fix anything, and at the end I always get the following message

Funny thing is that my apt-get system works perfect on Console. I can update my system through apt-get update, apt-get upgrade etc..

So.. how can I fix the graphic interface? I understand that my apt-get system is not broken, but somehow its GUI it is.

Any thoughts about it?

THANKS!

P.D: I have already tried sudo dpkg --configure -a and sudo apt-get autoremove
