# 统一的 apt 安装入口，解决 CI 偶发卡死在 apt 步骤上的问题。
|
|
#
|
|
# 背景：GitHub runner 上 apt 有两个"无限等"的坑
|
|
# 1) 网络：apt 默认没有连接超时，Azure 镜像抽风时会一直挂在 "0% [Connecting to ...]"
|
|
# 2) 锁：dpkg 锁被后台的 unattended-upgrades / apt-daily 占用时，apt 默认无限等待
|
|
# 本脚本给两者都加上上限，并做 3 次重试 + 换源兜底。
|
|
#
|
|
# 用法: bash .github/scripts/apt-install.sh gcc-mingw-w64-x86-64 build-essential
