"Couldn't find package language-pack-kde-zh"and the solution

[super_phoenix]

After I type in "sudo apt-get install language-pack-kde-zh language-pack-kde-zh-base language-pack-zh language-pack-zh-base language-support-zh", ubuntu returns a message:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package language-pack-kde-zh

What's the matter here and how to solve it?


NOW, this problem has been solved:
It is that I didn't type in the following that this problem was given risen to:
sudo apt-get update
sudo apt-get dist-upgrade
