Linux flash插件更新及最新sources.list

今天更新了几个软件，发现其中flashplugin-nonfree更新失败

正在设置 flashplugin-nonfree (9.0.48.0.2+really0ubuntu12.1) ...
Installing from local file /var/cache/flashplugin-nonfree/install_flash_pla
yer_9_linux.tar.gz
md5sum mismatch install_flash_player_9_linux.tar.gz
The Flash plugin is NOT installed.

网上搜了一下，原来是个Bug。

解决办法是：删除/var/cache/flashplugin-nonfree/目录中的文件，按Bug report中给出的方法“IMPORTANT NOTICE no.2”，清除cache，purge掉flashplugin-nonfree，为了保证源是最新的，我注释掉了cn99的源，使用了archive.ubuntu.com的，重新update后，再全新安装flashplugin-nonfree，一切还算顺利，有个小尾巴是，最后检查的时候发现还是从cn99下的：

apt-cache policy flashplugin-nonfree
flashplugin-nonfree:
已安装：9.0.48.0.2+really0ubuntu12.1
候选的软件包：9.0.48.0.2+really0ubuntu12.1
版本列表：
*** 9.0.48.0.2+really0ubuntu12.1 0

不清楚是怎么回事。更新是确实的，因为上news.163.com不再崩溃了，为了看“老衲”以及诸位淫才的评论，昨晚还崩溃了一次，呵呵。

另附上我自己使用的sources.list：
