|
||
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
|
||
|
||
**重要**:在升级之前,保险起见,不要忘了将你的数据在U盘或外部硬盘上保存一下。
|
||
|
||
### 桌面升级 ###

||
|

在升级之前,我们要先更新系统。打开终端输入以下命令
|

|
||
|
||
重启你的电脑以完成更新。
|
||
|
||
然后输入下面的命令来升级到新的可获得的版本
|
||
|
||
sudo update-manager -d
|
||
|
||
软件更新器会出现并且搜索新的发行版。

|
||
|
||
你可以开始使用新的ubuntu版本了。
|
||
|
||
### 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命令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。
