执行命令更新

复制代码

代码如下:

sudo apt-get update

使用sudo apt-get update问题总结

复制代码

代码如下:

sudo apt-get update

显示为

E: 无法获得锁 /var/lib/apt/lists/lock - open (11 Resource temporarily unavailable)E: 无法对状态列表目录加锁

直接把lock 文件删除就是了..

sudo rm /var/lib/apt/lists/lock

我在网上查了一下，还有下面方法

先查看一下是否有使用apt-get的程序,终端输入:ps -aux,找到使用apt-get的程序(最后一列),查看其PID号,然后杀死其进程,输入sudo kill PID,然后升级一下软件源,sudo apt-get update,sudo apt-get dist-update.

Ubuntu 更新软件源出错问题

当执行sudo apt-get update来更新软件源时，若出现以下类似错误： Failed to fetchSomething wicked happened resolving 'cn.archive.ubuntu.com:http' (-5 - No address asSOCiated with hostname)

说明DNS解析出现了问题，应着重查看以下方面：

1. cat /etc/resolv.conf

查看里面的domain, search和nameserver配置是否正确。

若通过代理上网，请查看：

2. cat /etc/apt/apt.conf

在里面添加设置：

Acquire::http::proxy "http://xxxxx.xxxxx.xxxx:1080" , 注意是http, 不是https

3. 查看 “系统”--> “首选项”--> “网络代理”，里面的代理是否设置正确
