Question

当我试图做百胜更新，有问题，你能告诉我哪里是问题吗？

我试图手动安装这些软件包，但失败了，不知道该怎么办？

更新：-我张贴yum更新输出也。

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Answer 1

我尝试了这么多命令，发现下面的命令非常有用。

# yum update --disableexcludes=main

Answer 2

我认为您的系统用于更新存储库的元数据已经过时。

由于找不到相应的perl-Git包更新，更新失败了。但是，我检查了我的本地CentOS镜像，正确的更新包就在那里。

因此，我怀疑您有一些旧的元数据用于更新回购。我建议您清除元数据，然后再尝试更新。

yum clean metadata

如果它仍然失败，问题可能是镜像，而不是你的系统。在这种情况下，只需等待24小时，希望镜像恢复同步。
