pacman -Syuu：错误：检索文件失败（“操作太慢”和“ SSL证书问题”）

Question

我想升级我的时候有麻烦便携式Msys2下10场有pacman -Syuu，详情如下。我之前没有做过这个。

问题和解决方案可能是什么？

按照这个，我的回购配置似乎还可以：

$ pacman-conf.exe

DBPath = /var/lib/pacman/
CacheDir = /var/cache/pacman/pkg/
HookDir = /etc/pacman.d/hooks/
GPGDir = /etc/pacman.d/gnupg/

编辑 在评论中建议我执行pacman-mirrors ... 。在我的系统中似乎没有这样的可执行文件（脚本，别名等）。另一方面，似乎我已经拥有了pacman-mirrors，并且它不提供任何可执行文件（在至少在msys2中）。它是否正确？

您可以使用参数禁用pacman的超时--disable-download-timeout。这样您就可以下载了

http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-qt5-5.12.1-5-any.pkg.tar.xz

在pacman的手册页中进行了描述。

另外--gpgdir指定GnuPG用于验证软件包签名的文件目录可能很有用。

另外，您可以考虑使用该参数--noconfirm 来绕过所有“确定吗？”消息。

关于我不确定的证书，也许本地路径配置不正确。不过，您有两个域，仍然由提供服务http。

在浏览器中，下载有效。刚刚完成，屏幕截图仍显示下载正在进行中：
