［已解决］pacman 出问题，不能更新也不能安装软件

[dongfanglu]

从2009.02的iso安装的系统，装完可以pacman -Syu，但是更新之后使用pacman就会出现No address record，再也不能更新也不能安装软件了，下了五月最新的iso文件，装完第一次pacman -Syu就会出现no address record

PS:baidu google 都可以ping得通，重装前的系统也出现这样的问题，并且firefox不能浏览外网，但是opera可以。

这个应该怎么解决呢？

今天终于解决这个问题了，看了arch官方论坛 glibc upgrade to 2-10.1-2 breaks dns for some programs 这个帖子，在resolv.conf开头添加options single-request 后就可以更新和安装软件了。

Try "options single-request" in /etc/resolv.conf, this should revert to the old glibc 2.8 behaviour.
In fact, it's a problem with your router or DNS server, not a bug in glibc.

检查/etc/pacman.d/mirrorlist

国内那两个是源的问题
自己用浏览器打开就知道了...=.=
fr那个我也不知道为什么不行，浏览器打开确实有archlinuxfr.db.tar.gz的，不过我没用过这个源

[dongfanglu]

源是没有问题的，因为更新前可以用，更新后才出现问题，而且我用opera可以打开，但是很奇怪firefox却不能打开，很苦恼

[jobinson99]

更新后你的mirrorlist全部被注释掉了哦！只剩国内两个，如果国内两个也连不上，就完全无法更新了。
把mirrorlist里面几个有用的取消注释吧。

国内的源是正常的，可以用。更新前我的mirrorlist就只有两个国内源，其他都被我注释掉了，更新后mirrorlist没有变化的。
我从网上查了很多资料，第一次认为是系统问题，重装，更新后又出现pacman 提示no address record，后来以为是ipv6 的问题，禁用了ipv6，发现firefox可以用了，但是pacman的问题依旧；现在认为可能是glibc升级造成的，不知道怎么解决了。

[HuntXu]

国内两个源我点击了进去都是404 not found
正常？

[dongfanglu]

我这里正常啊，用opera firefox都可以打开的，我的是教育网
