apt-get 更新 常見的有兩種 (其它特殊的更新在此略過)
1. sudo apt-get upgrade
upgrade is used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list. Packages currently installed with new versions available are retrieved and upgraded; under no circumstances are currently installed packages removed, or packages not already installed retrieved and installed. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version. An update must be performed first so that apt-get knows that new versions of packages are available.

2. sudo apt-get dist-upgrade
dist-upgrade dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. So, dist-upgrade command may remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files. See also apt_preferences(5) for a mechanism for overriding the general settings for individual packages.
使用 dist-upgrade 要謹慎 因爲他會移除 一些檔案 所以不建議 新手使用

3. 你在 軟體更新 看到的 可能是 upgrade
如果 你從 終端機 執行
sudo apt-get dist-upgrade
也許 你的困擾 就不見了
但是 要執行以前 最好先 學會 把 Ubuntu 備存起來 風險比較小
