求助:pacman -Syu 更新因网络问题失败

zi · December 20, 2025, 4:53pm

报错如下，更新必须使用科学上网(运营商:中国移动)，请问还有什么源可以用的，谢谢
另:

在9月份的时候，ustc和清华源无异常，是最近几个月出现的问题。先是镜像源连接速度慢，然后是清华源无法使用，现在是必须使用科学上网.
无防火墙

curl出来是这样的，谢谢

不过这个周情况好转了，现在就阿里镜像报错(“错误：无法从 mirrors.aliyun.com : Operation too slow. Less than 1 bytes/sec transferred the last 10 seconds 获取文件 'core.
db'“)，可能是上个周我这的移动抽风了(?)，毕竟我这可是连cf控制台都上不去的神秘网络，也是打扰了

不过

没问题呀。那你sudo curl -v https://mirrors.aliyun.com也是这样的吗？
