archlinux failed retrieving file 'core.db' from xxx-Linux-何三笔记

问题

今天在升级archlinux系统时提示：

$ yaourt -Syu
:: Synchronizing package databases...
error: failed retrieving file 'core.db' from mirrors.zju.edu.cn : Failed to connect to mirrors.zju.edu.cn port 80: Connection refused

很明显是mirrors.zju.edu.cn的服务器出了问题

解决

编辑 /etc/pacman.conf 文件

编辑vim /etc/pacman.conf在最后将Server = https://mirrors.zju.edu.cn/archlinuxcn/$arch注释掉，并添加Include = /etc/pacman.d/archlinuxcn-mirrorlist，如下

[archlinuxcn]
#The Chinese Arch Linux communities packages.
#Server = http://repo.archlinuxcn.org/$arch
#Server = https://mirrors.zju.edu.cn/archlinuxcn/$arch
Include = /etc/pacman.d/archlinuxcn-mirrorlist

添加 archlinuxcn-mirrorlist 文件

在/etc/pacman.d/目录下添加 archlinuxcn-mirrorlist文件 vim /etc/pacman.d/archlinuxcn-mirrorlist

## 上海科技大学 (上海) (ipv4, http, https)
#Server = https://mirrors-wan.geekpie.club/archlinuxcn/$arch
