Senior Lisandro,Thanks for answer, this is the output of the command, please let me know how to fix, apparently loopback is not running:

I don't see any 'lo'.
However, /etc/network/interfaces seems to be OK:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

Programs okular, k3b, korganizer, fail to launch, there may be others that I have not tested yet. While making a full backup, Clonezilla could not verify the integrity of the images.debsums to the rescue :)I have tested hard drive extensively with smartmontools, no errors. I have submitted bugs for all these, no response yet.If you have multiple bugs like this it sounds more a problem in your setup (either hardware or software) than an app's fault. I'm pretty sure those are all invalid ones.Above mentioned programs do launch eventually, after several minutes, and throw errors.This along says a lot. Please take a look at <http://perezmeyer.blogspot.com.ar/2012/11/is-your-kde-slooooow-check-your.html> If you happen to fins the cause of your problem please close all the bugs you filed. Kinds regards, Lisandro.
