Failed to update Plesk v. 12.0.18

[Kyle.A]

Hi,

I was looking for a little advice if possible, I have searched around and found a couple of pages relating to this but I'm not sure if any of the suggested solutions apply, here is the info:

Your operating system ( Ubuntu Server 14.04 LTS with Plesk 12.5 (64-bit) )
Your current used Plesk- Product ( Plesk v. 12.0.18 )

The last couple of update have failed to run the error as far as I can see is the following:

The following packages have unmet dependencies:
 linux-headers-generic : Depends: linux-headers-3.13.0-66-generic but it is not going to be installed
 psa-updates : Depends: sw-engine (>= 2.13.13) but 2.13.12-ubuntu1404.201502091720 is to be installed

Here is the most of the log file as the post can only support 1000 characters:
