由于“解析时发生了一些异常”错误，无法安装软件包

我正在跟进这些说明在我的笔记本电脑上安装 git。
当我这样做时：

$ sudo apt-get install git-core

这是我的终端显示的内容：

我该如何安装git在 Ubuntu 12.10 上？我甚至无法从 Ubuntu 软件中心做到这一点。

提前致谢！

答案1

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。

现在您应该删除锁定的文件：

您可以使用以下方式删除锁定文件

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

经过：这个答案

现在你应该打开一个终端并运行：

 sudo apt-get update --fix-missing

现在您可以再次安装所需的一切。
祝您有美好的一天

答案2

您是否设置了静态 IP /etc/networks/interfaces？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/etc/resolv.conf，无论您在其中设置什么，它都会在重新启动时被覆盖。解决方案是添加/etc/networks/interfaces以下内容：

dns-nameservers `<IP address of the DNS server>`
dns-domain `<the name of the domain>`

一个快速解决方法是添加名称服务器在 resolv.conf 中，但它会在您重新启动后消失。

答案3

添加/etc/network/interfaces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

当我调试时，/etc/resolv.conf在名称服务器不存在。因此我添加了以下几行：

nameserver 8.8.8.8
nameserver 192.168.1.1

然后就照做了sudo apt-get update。它就起作用了。

答案4

nano /ect/resolv.conf

删除所有

添加

“名称服务器 8.8.8.8”

保存并离开。

再次尝试“apt-get update”，它应该可以工作。
