unmet dependencies

[Riccardo Mottola <riccardo.mottola@libero.it>]

Hi all,

I run apt-get update and then upgrade tells me:

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 gnupg : Breaks: dirmngr (< 2.1.17-2) but 2.1.16-2 is installed
         Recommends: dirmngr (= 2.1.17-2) but 2.1.16-2 is installed
         Recommends: gnupg-l10n (= 2.1.17-2) but it is not installed
 hurd : Depends: hurd-libs0.3 (= 1:0.8.git20161120-1+b2) but 
1:0.9.git20161219-1 is installed
        Recommends: bf-utf-source but it is not installed
E: Unmet dependencies. Try using -f.


what should I do_ apparently hurds wants an aolder version of hurd-libs, 
but the last time I upgraded, the system was consistent.
