ubuntu 7.10 能上网，也能ping通源，就是不能升级，怎么回事啊。在software soure也不能找到最好的源，就是说在这个地方不能ping通，但是在命令行下可以。真是搞不明白，对了，我用的是校园网，那位大侠帮帮忙

楼主有没有换源试试。教育网推荐上海交大

还是不行，应该不是源的问题，感觉就像apt-get 一更新就不能连到网络一样。但是，网确实是连着的，能打开外网。寻找最快的源，都没有回应。是不是有什么设置不对啊。实际上在我装机过程中，就有一个更新过程，但是不能更新，装了很长时间，就把更新自动跳过了。谁还碰到过这样的问题啊？

就是这样的情况，用什么源都是这样。

有很多人在5.31的时候出现了这样的情况，我用的是CN99的源，也出现了类似的情况，暂时还没有高手回答这个问题，也没有得到官方的说明。

我看你的源添加的是8.04的，换一下。

仔细看WIKI

选智能升级试试

lz源都加错版本了

别的我也用了，能用的源我都试过了，都是这样的问题。我怀疑是不是学校防火墙给过滤掉了。从装了也是这种情况。我在实习公司用就没有问题。真搞不清楚

前几天我的问题已经解决了，安装系统都没有问题，原因可能linux出路由器要windows下的验证，就是升级连不到网络，我猜测原因是这样。解决办法就是，随便在同一局域网中找台windows机器做代理，ubuntu通过代理更新和升级，这样就搞定了。让它自动寻找最快的源，台湾的那个最快。
