I im trying to do 

sudo apt-get update

but i get the following error:

W: Failed to fetch http://ftp.udc.es/ubuntu/dists/trusty/Release  Unable to find   expected entry 'main/binary-x8-64/Packages' in Release file (Wrong sources.list entry or malformed file)

I have tried resetting the /etc/apt/sources.list like is here suggested:

How do I restore the default repositories?

And also tried to select another server from which to download the updates: 'sudo apt-get update' error on Ubuntu 12.04

But I keep getting the same damned error message. Any ideas?

As asked in comment, doing:

$ grep -R ftp.udc.es /etc/apt/sources.list*
/etc/apt/sources.list:deb http://ftp.udc.es/ubuntu/ trusty main universe
/etc/apt/sources.list.save:deb http://ftp.udc.es/ubuntu/ trusty main

$ cat sources.list
## See sources.list(5) for more information, especialy
# Remember that you can only use http, ftp or file URIs
deb http://ftp.udc.es/ubuntu/ trusty main universe
# CDROMs are managed through the apt-cdrom tool.

$ dpkg --print-architecture 
amd64
$ dpkg --print-foreign-architectures

As can be seen from the output of dpkg --print-foreign-architectures, you have a bunch of invalid architectures added, for some reason. Remove them:

sudo dpkg --remove-architecture x8664
sudo dpkg --remove-architecture x8-64
sudo dpkg --remove-architecture x864

In future, do check what you're adding.

Try adding these to your /etc/apt/sources.list . These are the us repositories.

deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted

deb http://archive.canonical.com/ubuntu trusty partner
deb-src http://archive.canonical.com/ubuntu trusty partner

you might get the error because Canonical has deprecated 14.04 ( before being blessed LTS) . If you are not on LTS then you should upgrade to 14.04.01 LTS.

You do that by running sudo do-release-upgrade

Go to Software and Update, and in Ubuntu Software tab, change the download location to Select best server. It will update the cache and after that, youer done. Then try apt-get update.
