psa-mnemo has unmet dependencies

[Priwac]

Hi,

I'm trying to "apt-get upgrade" but I'm getting the following error:

root@server:~# apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
psa-mnemo : Depends: psa-horde (>= 5.1.6) but it is not installed
Depends: psa-imp (>= 6.1.7) but it is not installed
E: Unmet dependencies. Try using -f.
root@server:~#

'apt-get -f install' not fixing the problem. Anything else I can do?

Thanks.
