我公司的電腦下載速度很慢,
利用 do-release-upgrade 來升級的,
據它的預估要5、6個小時以上
我想利用下班前下指令執行升級
然後第二天早上再看看結果

可是,升級中會問東問西,若沒回答的話,程式就卡住不動,
想請教諸位先進,有沒有什麼辦法,讓它能夠從頭跑到尾,
自動完成呢?

或者是,有沒有其它比較有效率的升級模式?

可以利用 screen 或是 tmux 這樣的程式

FourDollars 寫到：
可以利用 screen 或是 tmux 這樣的程式

非常感謝指點,
可小弟才疏學淺
Google了一下,實在看不懂如何使用於升級作業
不過,還是很感謝!

拿光碟升級看看吧

指令模式都問東問西

試試看 以下方法 The Debian way of upgrading
Please be aware that this method is valid, yet not officially advised by the Ubuntu developers.

建議：先備存你的 ubuntu server 作業系統

把下列指令寫在 script 檔 並且給予 可執行屬性：

sudo apt-get install aptitude # 如果你沒安裝這個套件 要先安裝這個套件
sudo aptitude update -y # 準備升級所有套件到最新版本
sudo aptitude safe-upgrade -y # 升級所有套件到最新版本
sudo sed -i.ORIG s/Natty/Oneiric/g /etc/apt/sources.list
# 把/etc/apt/sources.list備份到/etc/apt/sources.list.ORIG
# 把/etc/apt/sources.list從Natty升級到Oneiric, 變成11.10的軟體來源
sudo mv /etc/apt/sources.list.d/ /etc/apt/sources.list.d.ORIG/
# 把第三方軟體來源的資料夾/sources.list.d/改名爲/sources.list.d.ORIG/備存起來
sudo mkdir /etc/apt/sources.list.d/
# 建立新的空的第三方軟體來源的資料夾/sources.list.d/
sudo aptitude update -y
sudo aptitude safe-upgrade -y
sudo aptitude full-upgrade -y
# 更新完畢
sudo rmdir /etc/apt/sources.list.d/
sudo mv /etc/apt/sources.list.d.ORIG/ /etc/apt/sources.list.d/
# 再把第三方軟體來源備存的資料夾/sources.list.d.ORIG/改回來/sources.list.d/
sudo aptitude update -y
sudo aptitude safe-upgrade -y
sudo aptitude full-upgrade -y
# 更新完畢
sudo shutdown -P now # 更新完畢 關機

實際執行更新
sudo script檔名

這個方法應該可以適用在任何版本 是 Debian 的方法 但未獲得 ubuntu 官方推薦
是否有風險 請你衡量 記得事先備存一份
歡迎 分享你成功或失敗的經驗

向poloshiao報告一下
依照您的script執行之後
沒有失敗訊息,也沒有問東問西
但也沒有成功
因為版本仍然停留在 11.04 版

另外,執行中好像看到一行訊息
sudo rmdir -f /etc/apt/sources.list.d/
-f 的選項無效

但這個似不影響執行

另外,執行中好像看到一行訊息 sudo rmdir -f /etc/apt/sources.list.d/ -f 的選項無效

對 rmdir 沒有 -f 選項
我有發現 但是忘了拿掉
謝謝你的更正

因為版本仍然停留在 11.04 版

你可以提供你更改後的這兩個檔案 貼上來嗎
1. sudo cat /etc/apt/sources.list
2. sudo cat /etc/update-manager/release-upgrades

/etc/apt/sources.list

# 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

家中的電腦已經升級至 11.10 了, 我可以把它的 /etc/apt/sources.list 拷貝至公司的電腦中,再重新執行一次嗎 ?

/etc/update-manager/release-upgrades
1. 使用 do-release-upgrade 來升級時
/etc/apt/sources.list 是 Natty
所以 Prompt=normal
才會 升級爲 Oneiric
2. 使用 script 檔升級
/etc/apt/sources.list 原是 Natty
但是已經使用
sudo sed -i.ORIG s/Natty/Oneiric/g /etc/apt/sources.list
更改爲 Oneiric
所以 Prompt=never 即可
實際上 script 檔執行時 可能沒有去核對這個設定 （猜測的）

2. /etc/apt/sources.list
都還是 natty
如果這是已經執行
sudo sed -i.ORIG s/Natty/Oneiric/g /etc/apt/sources.list
的結果
那就表示 這個指令沒效果
這是 原稿的指令
現在 改成兩個 指令 來取代:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.ORIG
sudo sed s/Natty/Oneiric/g /etc/apt/sources.list # 把 前後''都拿掉
請你先把 script 改改看
註：你可以先實驗看看這個指令執行有沒有效
然後 sudo cat /etc/apt/sources.list 看看 Natty 有沒有全部改爲 Oneiric
但是記得把 /etc/apt/sources.list.ORIG 再 覆蓋 /etc/apt/sources.list 回來

3. 你要把備存的檔案 回存 再重新執行 script 檔
希望 你這次能成功

4. 這是(我所知道）第一次 有人嘗試這樣更新版本 希望你的先鋒 能夠造福其它網友

5. 辛苦您啦 ! 如果還有錯誤訊息 把 錯誤訊息 copy 上來 我們一起來找原因

sudo sed s/Natty/Oneiric/g /etc/apt/sources.list

這行指令無效，我覺得問題似乎是出在大小寫上頭

若改成

sudo sed s/natty/Oneiric/g /etc/apt/sources.list

也就是 Natty 要改成 natty

如此一來，那麼，Oneiric 要不要一併改成 oneiric 呢 ?
