如果想从Ubuntu14.04/13.10/13.04/12.10/12.04或者更老的版本升级到14.10，只要遵循下面给出的步骤。注意，你不能直接从13.10升级到14.10。你应该先将13.10升级到14.04在从14.04升级到14.10。下面是详细步骤。
下面的步骤不仅能用于14.10，也兼容于一些像Lubuntu14.10，Kubuntu14.10和Xubuntu14.10等的Ubuntu衍生版本
服务器升级
从ubuntu14.04的服务器升级到14.10的服务器，采用下面的步骤。
安装update-manager-core 这个包如果之前没唷安装的话：
sudo apt-get install update-manager-core
编辑 /etc/update-manager/release-upgrades这个文件。
sudo nano /etc/update-manager/release-upgrades
像下面那样设置Prompt=normal或者Prompt=lts
# Default behavior for the release upgrader. [DEFAULT] # Default prompting behavior, valid options: # # never - Never check for a new release. # normal - Check to see if a new release is available. If more than one new # release is found, the release upgrader will attempt to upgrade to # the release that immediately succeeds the currently-running # release. # lts - Check to see if a new LTS release is available. The upgrader # will attempt to upgrade to the first LTS release available after # the currently-running one. Note that this option should not be # used if the currently-running release is not itself an LTS # release, since in that case the upgrader won't be able to # determine if a newer release is available. Prompt=normal
现在可以通过下面的
来更新你的服务系统了。
sudo do-release-upgrade -d
直到屏幕提示你已完成。
