【问题描述】:
当我尝试更新 EC2 Amazon Linux 实例时,我收到以下错误:
加载的插件:extras_suggestions、langpacks、priorities、update-motd 无法检索镜像列表 http://amazonlinux.ap-south-1.amazonaws.com/2/core /latest/x86_64/mirror.list 错误是 12:http://amazonlinux.ap-south-1.amazonaws.com/2/core/latest/x86_64/mirror.list 上的超时:(28,'连接在 5000 毫秒后超时')
其中一个配置的存储库失败(未知), 并且 yum 没有足够的缓存数据来继续。此时唯一 百胜可以做的安全的事情是失败。有几种方法可以“解决”这个问题:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
找不到 repo 的有效 baseurl:amzn2-core/2/x86_64
任何帮助将不胜感激。

EC2 实例是否在公有子网中(连接到 Internet 网关)?超时表明它没有与 Internet 的网络连接。
