Ubuntu 软件仓库

本镜像仅包含 32/64 位 x86 架构处理器的软件包，在 ARM(arm64, armhf)、PowerPC(ppc64el)、RISC-V(riscv64) 和 S390x 等架构的设备上（对应官方源为 ports.ubuntu.com）请使用 ubuntu-ports 镜像。

对于 Ubuntu 不再支持的版本，请参考 Ubuntu 旧版本帮助。

在 Ubuntu 24.04 之前，Ubuntu 的软件源配置文件使用传统的 One-Line-Style，路径为 /etc/apt/sources.list；从 Ubuntu 24.04 开始，Ubuntu 的软件源配置文件变更为 DEB822 格式，路径为 /etc/apt/sources.list.d/ubuntu.sources。

我正在使用什么版本的 Ubuntu？ 可以通过以下命令查看当前系统版本：

cat /etc/os-release

例如在 Ubuntu 24.04 下，文件内容如下：

PRETTY_NAME="Ubuntu 24.04.1 LTS"

NAME="Ubuntu"

VERSION_ID="24.04"

VERSION="24.04.1 LTS (Noble Numbat)"

VERSION_CODENAME=noble

ID=ubuntu

ID_LIKE=debian

HOME_URL="https://www.ubuntu.com/"

SUPPORT_URL="https://help.ubuntu.com/"

BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"

PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"

UBUNTU_CODENAME=noble

LOGO=ubuntu-logo

VERSION_ID 后面的版本号即为当前系统版本，VERSION_CODENAME 后面的是代号。代号在软件源配置文件中会被使用。请注意在下面的配置中选择符合你的机器的版本号，在替换配置前确认代号一致，否则之后的更新操作可能导致系统出现问题。

配置内容 将系统自带的对应文件做个备份，然后根据格式的选择下面对应的内容替换，即可使用选择的软件源镜像。

因镜像站同步有延迟，可能会导致生产环境系统不能及时检查、安装上最新的安全更新，不建议替换 security 源。
