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
。
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。
