Also running Mint 17.2 here. Your 'apt-cache policy gnucash' command indicates you don't have the getdeb repositories properly installed. You're only being offered gnucash from the trusty/universe repository.

You could try installing the getdeb repository again. Or you could just add it manually by creating a file called /etc/apt/sources.list.d/getdeb.list and adding the following line in it:

deb http://archive.getdeb.net/ubuntu trusty-getdeb apps

(you'd need to do this using root permissions. eg. sudo nano /etc/apt/sources.list.d/getdeb.list )

Once you have that, do another 'apt-get update' and check with 'apt-cache policy gnucash'. You should see 2.6.8 as a candidate as well as the 2.6.1 version. (see below)
then 'apt-get upgrade'

Watch for errors during the update process. If it mentions a key error, you may have to re-add the getdeb keys. 

P.

For reference, my policy output is this.
