Did you upgrade to Kubuntu 14.04 Trusty Tahr or Kubuntu Utopic Unicorn 14.10? 14.10 is in your question, 14.04 is in the results you posted. The procedure to go from 13.10 to 14.04 or 13.10 to 14.10 is very different. Please explain how you upgraded.

Hi thanks for your reply.
I just used the upgrader tool, as I am seeing notifications. It tries to update to Kubuntu 14.04.
Should I try 14.10 instead ?

There seem to be wrong repository servers in your sources.list configuration files.

The "normal" repository servers countrycode.archive.ubuntu.com have only packages for i386 and amd64 architecture.
If your system is based on the armhf architecture, you have to use the ports.ubuntu.com repository server.

What is the output of the following terminal commands:

uname -a
lsb_release -a
dpkg --print-architecture
dpkg --print-foreign-architectures
find /etc/apt -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;

And in any case, you cannot leapfrog releases in an upgrade, so you have to go from 13.10 to 14.04 and cannot directly go to 14.10.

The results of the commands is the following:

Do I have to change the repository server because of the foreign architecture ? if yes how ?

According to the output of "uname -a", you are running a kernel for "x86_64" also known as "amd64" architecture, that is the 64 bit version for Intel and AMD CPUs.
Due to the fact that some packages are only provided in a 32 bit variant, such system needs "i386" as foreign architecture.
You package management system, however, has also "armhf" as foreign architecture. Is there a specific reason for this? In my humble opinion this is nonsense, because I am not aware of any CPU that would be capable of using the i386/amd64 and the armhf instruction set at the same time.

I assume that the solution for you must be to remove the definition of armhf as foreign architecture with the command
sudo dpkg --remove-architecture armhf

Then the upgrade to 14.04 should work without problems.

Thanks a lot. I follow your advice and remove armhf.
The upgrade worked perfectly.

Thanks !
