How can I install the package iftop?
I installed Ubuntu 12.04 and it's not updating when I try. I changed may server address for Ubuntu and DNS but it's still not working. I'm trying to install iotop but it doesn't. I have already changed my Ubuntu server location and changed DNS to Google's default server. I have already installed Zental correctly, but iotop doesn't appear, how can I install it?
Here the error log:

E: Unable to locate package iftop
Solution 1:
From your comment, it seems that you are trying to install iftop, but it's telling you it's not there.
iftop is in the Universe repository, so you need to enable it. Visit this question: How do I enable the "Universe" repository? to enable it. When you enable it, first do apt-get update, then try apt-get install iftop.
The correct command to update your package list is:
sudo apt-get update
Then, the command to actually upgrade your Ubuntu (i.e. download and install the newer versions of packages) is:
sudo apt-get upgrade
See my answer to this question: https://askubuntu.com/a/344363/52726 for a little bit more explanation on the difference between
apt-get updateandapt-get upgrade.
The command to install packages (or "applications") is:
sudo apt-get install <packagename>
Where <packagename> is the name of the application. For example skype, vlc, and so on.
The command you ran, apt-get install update is telling Ubuntu to install a package called update, which doesn't exist.
