gcc-4.5 installation problem
 

Hi
I have with Windows 7 like host a virtual machine Vbox with Ubuntu 14.04, to use with OpenFoam (CFD software). With the version 2.2.1 it worked perfect, but I wanted install the old version 1.7.1 because of a misunderstood mistake with a mesh. Anyway, I followed the instruction from here http://openfoam.org/download/1-7-1-ubuntu/, but I dunno what I did wrong that I couldn’t install the version, plus I uninstalled the version 2.2.1. So after that, always I opened the console I got this message:
(Image 1)
No existe el archive o directorio: The file or directory doesn’t exist.
I deleted all folders of OpenFoam and I started to install it from other link, https://openfoamwiki.net/index.php/I...M-1.7.1/Ubuntu. But when I trying to install the library gcc-4.5 I get always this error.
*sorry for the spanish, I dunno how change it to English, but here translating the sentences.

It might meaning you have requested an imposible situation or, if using the distribution unstable that some required package haven’t been created or been moved out of incoming.

I have tried to install old and last versions, to repair the broken packages with the Synaptic option.

Also I tried the instruction in this link, but I dunno how identified the rebel package to delete the lines http://www.adslzone.net/postt290764.html
Also have tried apt-get update; apt-get upgrade… as this link http://askubuntu.com/questions/15440...-04-lts/154406
Also to install build-essential, getting the same error plus I couldn’t sharing folder with the host anymore, so I uninstalled it.
Also apt-get autoremove, dist-update, dist-upgrade from this list which I found, http://www.preguntaslinux.org/-howto...de-t-5780.html and nothing.
Also I read this one http://www.ubuntu-es.org/node/74339#.VzKfjISLSM8, in which he deleting and reinstalling the two package which had dependence, but I have a lot!!
By last I get in of sudo gedit /var/lib/dpkg/status like i saw at http://www.adslzone.net/postt293517.html but the file is enormous and I dunno well what I’m looking for.
