404无法获取包
好的，所以我对此很陌生，所以我可能不会给你适量的信息，但我希望这对我很有帮助。
我正在运行Ubuntu 14.10LTS（甚至认为我的/etc/apt/source.list说了一些关于13.10的内容）我只是说明了这个“404 not found”和“未能获取”，我试过做sudo apt-get dist-upgrade ， sudo sed -i -e 's/archive.ubuntu.com\|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list grep -E 'archive.ubuntu.com|security.ubuntu.com' /etc/apt/sources.list.d/*但他们还没有工作，我认为最后两件事情变得更糟。

最好将sources.list重置为默认值。 完全替换/etc/apt/sources.list ：
###### Ubuntu Main Repos deb http://us.archive.ubuntu.com/ubuntu/ utopic main restricted universe multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ utopic main restricted universe multiverse ###### Ubuntu Update Repos deb http://us.archive.ubuntu.com/ubuntu/ utopic-security main restricted universe multiverse deb http://us.archive.ubuntu.com/ubuntu/ utopic-updates main restricted universe multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ utopic-security main restricted universe multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ utopic-updates main restricted universe multiverse ###### Ubuntu Partner Repo deb http://archive.canonical.com/ubuntu utopic partner deb-src http://archive.canonical.com/ubuntu utopic partner ###### Ubuntu Extras Repo deb http://extras.ubuntu.com/ubuntu utopic main deb-src http://extras.ubuntu.com/ubuntu utopic main
然后做sudo apt-get update ，404应该停止。
备份sources.list之前你做一些破坏性的事情就像将来的就地sed替换一样（例如sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup 。
希望有所帮助！
注意：我使用http://repogen.simplylinux.ch/根据您当前的sources.list松散地生成上述源代码 – 如果您想调整它，请查看它。
问题是14.10不再维护。
我按照https://smyl.es/how-to-fix-ubuntudebian-apt-get-404-not-found-package-repository-errors-saucy-raring-quantal-oneiric-natty/进行了操作：
正常的Ubuntu版本支持9个月，而LTS（长期支持）版本支持5年。 一旦支持Ubuntu版本，您使用的存储库将被移动到另一台服务器，并且将不再在标准的http://archive.ubuntu.com/ubuntu/dist/位置上提供。
