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.’ -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 "" , 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
