求助：ubuntu 11.04使用apt-get安装软件时一直提示E:unable to locate package

环境，VMware虚拟机安装了ubuntu 11.04，在使用apt-get安装软件时一直提示E：Unable to locate package。
百度了原因，说是要更新源，使用命令：sudo apt-get update更新了，更新之后问题还是存在；
然后在网上搜索了源，将那个台湾源和网易的源都更新到了/etc/apt/source.list文件中；然后再sudo apt-get update，更新之后，问题还存在，现在不知道怎么搞了，在网上搜索原因都是说没有更新，他们更新之后都成功了，我更新之后还是一直Unalbe to locate package，请大家帮忙看一下，谢谢；

不知道楼主对14.04有什么体会，个人感觉出现了中文的字体很不舒服。

问题解决了，还是源的问题，网上找的那些源都是很久以前的了，很多的可能都不能用了； 自己重新下载了一个ubuntu 14.04版本装上，这个可以正常使用，然后将这个里面的更新源地址放原来那个里面去，运行sudo apt-get update更新后就可以按转软件了。 更新源地址（这是Ubuntu 14.04的/etc/apt/source.list文件的内容）： #deb cdrom:[Ubuntu 14.04 LTS _Trusty Tahr_ - Release amd64 (20140417)]/ trusty main restricted # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://us.archive.ubuntu.com/ubuntu/ trusty main restricted deb-src http://us.archive.ubuntu.com/ubuntu/ trusty main restricted ## Major bug fix updates produced after the final release of the ## distribution. deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.
