我的解答思路和尝试过的方法

已更新源

我想要达到的结果

取消/删除i386包强制安装更新

Ubuntu取消自动更新命令

1.

复制代码

代码如下:

vi /etc/apt/apt.conf.d/50unattended-upgrades

Unattended-Upgrade::Allowed-Origins {

// "${distro_id}:${distro_codename}-security";

// "${distro_id}:${distro_codename}-updates";

// "${distro_id}:${distro_codename}-proposed";

// "${distro_id}:${distro_codename}-backports";

};

注释掉选项相应的选项。

2.

复制代码

代码如下:

vi /etc/apt/apt.conf.d/10periodic

APT::Periodic::Update-Package-Lists "1"; //显示更新包列表 0表示停用设置

APT::Periodic::Download-Upgradeable-Packages "1"; //下载更新包 0表示停用设置

APT::Periodic::AutocleanInterval "7"; // 7日自动删除

APT::Periodic::Unattended-Upgrade "1"; //启用自动更新 0表示停用自动更新

本次安装的ubuntu11.04没有此文件，所以在/etc/apt/apt.conf.d下寻找有如下文字的文件，找到了20auto-upgrades

复制代码

代码如下:

APT::Periodic::Update-Package-Lists "0";

APT::Periodic::Unattended-Upgrade "0";

将其修改
