ubuntu update,

首先尝试;

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

 如果还不行,依照下面的来操作,笔者就是按下面操作成功解决问题.

If you still have issues, then change your repo mirror: Open Update Manager or Software Updater, then click Settings > Ubuntu Software tab, then select Other from the Download From menu and click the Select Best Server button. Now try updating/upgrading again.
