无法应用 yum update 或安装任何东西

Question

在 AWS 上创建 EC2 实例后，我已使用 SSH（PEM 文件）连接到服务器，我正在尝试在服务器上安装 Cpanel，但在尝试更新或安装任何东西时出现此错误.

我的命令：

 yum update

我得到的错误：

amzn2extra-docker                                                                                      | 3.0 kB  00:00:00

Trying other mirror.


One of the configured repositories failed (Vesta - cmmnt),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:

  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=vesta ...

  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 vesta
     or
         subscription-manager repos --disable=vesta

  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=vesta.skip_if_unavailable=true

failure: repodata/repomd.xml from vesta: [Errno 256] No more mirrors to try.

Answer 1

我已经尝试了错误建议的选项，但没有一个有效，这是我解决这个问题的方法

cd /etc/yum.repos.d

然后

rm vesta.repo

现在 Yum 更新和安装任何包都可以了。

Answer 2

可能是vesta repo的url不正确。
无论如何，如果你不需要它，你可以删除它，就像你一样。
但是你也可以只禁用那个有问题的回购：
sed -i 's/enabled=1/enabled=0/g' /etc/yum.repos.d/vesta.repo
