由于“恶意发生了解决”错误，无法安装软件包
我按照这些说明在我的笔记本电脑上安装git。
当我做：
$ sudo apt-get install git-core
这就是我的terinal所展示的：

我怎么能在Ubuntu 12.10上安装git ？ 我甚至无法从Ubuntu软件中心这样做。
提前致谢！
关闭所有与安装软件有关的程序/窗口，例如Synaptic，软件中心和终端。
现在你应该删除锁定的文件：
您可以删除锁定文件
sudo rm /var/lib/apt/lists/lock您可能还需要删除缓存目录中的锁定文件
sudo rm /var/cache/apt/archives/lock通过： 这个答案
现在你应该打开一个终端并运行：
sudo apt-get update --fix-missing
现在你可以再次安装你想要的一切。
祝你今天愉快
你有/etc/networks/interfaces设置的静态IP吗？ 升级到Ubuntu 12.04后，我遇到了类似的问题。 问题是DNS服务器不再设置在/etc/resolv.conf ，无论你放在那里它都会在重启时被覆盖。 解决方案是在/etc/networks/interfaces添加：
dns-nameservers `` dns-domain ``
快速修复是在resolv.conf中添加名称服务器 ，但重启后它会消失。
在/etc/network/interfaces添加了以下内容：
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.205 netmask 255.255.255.0 gateway 192.168.1.1
在调试时，在/etc/resolv.conf ， 名称服务器不在那里。 所以我添加了以下几行：
nameserver 8.8.8.8 nameserver 192.168.1.1
然后做了sudo apt-get update 。 它刚刚起作用。
nano /ect/resolv.conf
删除所有
加上这个
“nameserver 8.8.8.8”
保存并离开。
再次尝试“apt-get update”，应该可以正常工作。
