I have a little problem updating my ubuntu. I have not update it for a while and I tried today. The problem is that I tried 3 time, and there is the same problem. The problem says something like this: "Error in validating some packages. Could not authenticate some packages. This may be due to temporary network problems. You can try later. Beneath you have a list of the packages that could not authenticate."

And there are a lot of packages.

For the other problems, I would recommend running all of the following commands:

sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get update
