我有一台執行 Debian 的 PowerBook G4。

我按照 debian wiki的說明進行操作，但對於安裝，它只是說

安裝 flashplugin-nonfree（來自 contrib 部分）。

我不確定那是什麼意思，所以我就跑了

apt-get install flashplugin-nonfree

但是得到了這個錯誤

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package flashplugin-nonfree is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'flashplugin-nonfree' has no installation candidate

這是我的sources.list-編輯：

#

# deb cdrom:[Debian GNU/Linux 7.3.0 _Wheezy_ - Official powerpc CD Binary-1 20131215-05:55]/ wheezy main

deb cdrom:[Debian GNU/Linux 7.3.0 _Wheezy_ - Official powerpc CD Binary-1 20131215-05:55]/ wheezy main

deb http://ftp.us.debian.org/debian/ wheezy main contrib non-free
deb-src http://ftp.us.debian.org/debian/ wheezy main

deb http://security.debian.org/ wheezy/updates main
deb-src http://security.debian.org/ wheezy/updates main

# wheezy-updates, previously known as 'volatile'
deb http://ftp.us.debian.org/debian/ wheezy-updates main
deb-src http://ftp.us.debian.org/debian/ wheezy-updates main
deb http://ppa.launchpad.net/webupd8team/java/ubuntu precise main
deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu precise main

新答案

對不起，我不夠謹慎。

在 PowerPC 上沒有對 Flash 的官方支持，您唯一的選擇是免費外掛“ gnash ”

sudo apt-get install gnash browser-plugin-gnash

---

舊答案

要將非免費應用程序添加到您的安裝源，請修改文件/etc/apt/sources.list：

sudo 'the_editor_of_your_choice' /etc/apt/source.list

~~將行編輯

deb http://ftp.us.debian.org/debian/ wheezy-updates main

為

deb http://ftp.us.debian.org/debian/ wheezy-updates main contrib non-free~~

編輯2：

deb http://ftp.us.debian.org/debian/ wheezy main

或

deb http://ftp.us.debian.org/debian/ wheezy main contrib non-free

然後執行那些行

#this is for updating ths list of app available in repository after the update made to your `source.list` file  
sudo apt-get update

# You might want to run this command to upgrade your packages:
sudo apt-get upgrade 

#this is the command to install flash on debian once you activate the nonfree and contrib repositories
sudo apt-get install flashplugin-nonfree

#this seems to be the command to update according to the [debian wiki][2]
sudo update-flashplugin-nonfree --install

這應該可以解決問題。
