Upgrading to 14.04 gives problems II

[J.L. Blom]

I decided to start a new subject as otherwise the thread is too long.
I have made progress, mostly by reinstalling some packages.
However, my main problem is still there. I cannot download wine as the 
system still says:
-----------------------------------------
  sudo apt-get install wine

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
  wine : Depends: wine1.6 but it is not going to be installed or
                  wine1.7 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
----------------------------------------
I´ve followed all advices also Nils who advised me to purge the system 
but to no avail.
I tried to use synaptic but that did - in a different way - the same.
I used ubuntu tweak to remove all cruft but still it complains that I 
have broken packages. My problem is also that the term ¨broken packages¨ 
is rather vague. It can mean all things from unavailable libraries to 
incorrectly downloaded parts.
My logwatch showed all packages removed and purged and there was only 
one package related to wine (wine1.6-i386:i386 
1:1.6.1-0ubuntu1~ppa1~precise1) but that had no effect as you can see.
The only option I have is to install from the official wine-site 
directly but I´m reluctant to do that as I don’t know what problems it 
can give. When I try to install with synaptic wine1.7 want to remove all 
sorts of other packages, a.o. dolphon, gimp, gnome-shell, imagemagick, 
libreoffice, nvidia-libopencl1-304, etc. and install all kind of i386 
libraries and packages. I don´t think I should do that as I need the 
packages like libreoffice daily.
The only advantage is that it didn’t give the broken packages but that 
appears when I try to install it.
I think I tried all possibilities I know of and would very much like to 
know how to solve this problem. I have installed other packages but that 
went smoothly
As to backup: I use backuppc on a daily bas so /home and /etc are saved.
