如何將 Ubuntu14.04 Server 安全的升級到14.10

如果想從Ubuntu14.04/13.10/13.04/12.10/12.04或者更老的版本升級到14.10，只要遵循下面給出的步驟。注意，你不能直接從13.10升級到14.10。你應該先將13.10升級到14.04在從14.04升級到14.10。下面是詳細步驟。

下面的步驟不僅能用於14.10，也兼容於一些像Lubuntu14.10，Kubuntu14.10和Xubuntu14.10等的Ubuntu衍生版本

重要：在升級之前，保險起見，不要忘了將你的數據在U盤或外部硬碟上保存一下。

伺服器升級

從ubuntu14.04的伺服器升級到14.10的伺服器，採用下面的步驟。

安裝update-manager-core 這個包如果之前沒唷安裝的話：

sudo apt-get install update-manager-core

編輯 /etc/update-manager/release-upgrades這個文件。

sudo nano /etc/update-manager/release-upgrades

像下面那樣設置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

現在可以通過下面的命令來更新你的服務系統了。

sudo do-release-upgrade -d

直到屏幕提示你已完成。
