關於 Eee PC 更新的一些注意事項
February 23, 2008 – 1:49 pm到目前為止，Eee PC 已經流行一段時間了，相信大家都經常看到一些修改、更新原系統的方法，不過有幾點，要留意一下，更新失敗是小事，要重裝的話就麻煩了。:-)
- 不要到處找 “deb 包” 安裝到 Eee PC，因為坊間的 deb 包主要分為兩類，一類是給 Debian 用的，一類是給 Ubuntu 用的，雖然 Eee PC “粗略地” 基於 Xandros (再粗略一點的是 Debian 的修改版)，但是因為要適應 Eee PC 的硬體環境和速度，很多時候都會修改了原來 Debian 的設定，如果直接拿 Debian 什至 Ubuntu 的 deb 包放進去，或者是直接加入 debian/ubuntu 的東西在 sources.list，然後隨便的安裝個什麼東西的話，很有可能會造成系統不一致，什至損壞。
例如幾個網友都遇到過的 “perl” 或者 “kde” 的應用程式問題，就是因為 Eee PC 跟正式 Debian 的包不兼容而引起的。 - 坊間有很多所謂 “直接在第一分割區上動手” 的更新方法，說可以節省第二分割區上的空間的方法，這個有一定危險性，而且就算安裝成功也會有問題，之前有些網友遇到過，我也解釋過一點，現在會詳細講解一下。
參考 XEPC.org 的其中一篇講解檔案系統的文章，就會知道 Eee PC 的檔案系統，其實是由兩個分割區組成，第一分區是唯讀，就是預設的檔案架構，而第二分割區是可讀寫的，“蓋上去” 第一分割區的東西，所有檔案的新增、移除、修改都是在第二分割區上“記載”著的，這也解釋了為什麼我們在 Eee PC 上“刪除”某些包的時候，硬碟空間不會增加。
正因為空間會越來越少，有些人就會想到 “把更新、移除、修改直接在第一分割區上做” 的方法，這些方法本質沒有什麼錯誤，可是都忽略了一些小事，但這些小事影響可真不小。
例如 apt-get / dpkg 的數據庫，因為不斷會被更新，所以它會出現在第二分割區上；又例如存放用戶的資料，密碼等的檔案 “/etc/passwd” 和其他系統設定都會在開機後被更新，所以也會在第二分割區，結果是當用戶安裝一些會新增系統用戶的軟體時，所新增的用戶並不會出現在系統上；更麻煩的是，被刪除的檔案不會真的被刪除，而是在第二分割區上 “標記” 成不存在而已，如果用戶在更新之前 “刪除”了某某檔案，而在第一分割區安裝東西時會安裝這個檔案的話，它在重新開機後都不會出現。所以，在第一分割區所做的東西不一定都會反映在系統上。
不過也有解決方法的，就是 F9 了，這樣所有的更新都會正確反映出來。這也是使用 XEPC.org 更新光碟之前要用 DVD / F9 還原的原因。
所以做這些動作之前要留意，不要盲目跟從一些坊間的方法。不過大家可以放心，這裡的軟體庫中的所有包都是完全適合 Eee PC 使用的。(呵呵)
PS. 最近幾天 XEPC.org 不是沒有更新啊，而是在弄第二版的 XEPC.org 更新光碟，而且會是重大更新，包括最新 kernel 和一系列的系統底層東西，希望早日測試成功。

感謝，這裡給予的幫助很大
十分希望，第二版的更新可以造福一下沒有外接光碟機的族群

Please reinstall those perl deb packages, download from ASUS web first:
http://update.eeepc.asus.com/p701/pool/libperl5.8_5.8.8-7_i386.deb
http://update.eeepc.asus.com/p701/pool/perl_5.8.8-7_i386.deb
http://update.eeepc.asus.com/p701/pool/perl-base_5.8.8-7_i386.deb
http://update.eeepc.asus.com/p701/pool/perl-modules_5.8.8-7_all.deb
and then use “sudo dpkg -i *.deb” to force re-installation of these files.

Re: Isabella
After download those deb files and save it, they should be in /home/user, right?
So now open a terminal window, and type
sudo dpkg -i *perl*deb
This should give you something like unpacking blah blah blah replacing blah blah blah and then it will finish without any errors.
If you are not sure, take a picture of the screen after the command.

Hi Fai,
after typing the command, actually is not exactly same as what u said, however i cannot paste the photo in here i can summerize in here as follow:
dpkg: unknown option -*
type dpkg –help xxxxxxxxx
use “dselect” or “Aptitude” for user-friendly package xxxxxx
type dpkg -Dhelp xxxxxxxx
type dpkg -force–help xxxxxxxx
type dpkg-deb –help for xxxxxxx
………………..
……………..
something like that!
what can i do then??

Re: Isabella
You have typed something wrong, the command should be:
dpkg[space]-i[space]*perl*deb[enter]
Make sure the space is correct, and make sure you saved the files under the directory /home/user
