Arch Linux安装执行pacstrap /mnt base base-devel需下载多少数据？

Hey there, fellow Arch newbie! I feel your pain—slow downloads during installation are the worst, especially when you're excited to get your system up and running. Let's break this down for you:

Total Download Size for base + base-devel #

The combined download size for the base and base-devel package groups (including all their dependencies) typically falls between 300–350 MB (this can vary slightly depending on your mirror and current package versions).

Quick Time Estimate #

At your current speed of 10 KiB/s:

• 1 MB = 1024 KiB, so 300 MB = 307200 KiB
• Total time needed at steady speed: ~307200 / 10 = 30720 seconds ≈ 8.5 hours
• If you’ve already been downloading for 2 hours, you’ve likely transferred ~72000 KiB (~70 MB), leaving ~230–280 MB remaining. That’s roughly 6–7.5 more hours at your current rate.

Fixing the Slow Network (Critical Tip!) #

Your 10 KiB/s speed is way below normal—this is almost certainly a mirror issue, not your internet connection. Here’s how to fix it mid-install:

1. Stop the current pacstrap process (press Ctrl+C; don’t worry, pacman will keep partial downloads and resume later)
2. Update your mirrorlist to use faster sources:
   • Open the mirrorlist file with nano: nano /etc/pacman.d/mirrorlist
   • Add a fast domestic mirror (if you’re in China) to the top of the list (this ensures pacman uses it first):

     Server = https://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch
     Server = https://mirrors.ustc.edu.cn/archlinux/$repo/os/$arch
     

   • Or use the reflector tool to auto-select the fastest, recently synced mirrors:

     reflector --latest 10 --sort rate --save /etc/pacman.d/mirrorlist
     

3. Restart pacstrap: Run pacstrap /mnt base base-devel again. Pacman will automatically resume downloading any partial packages, and you should see a massive speed boost.

This should cut your installation time from hours to minutes—trust me, it’s worth the detour!
