不确定我是否应该在这里问这个问题，但目前我很困惑。
我不是 Linux 方面的佼佼者，但可以应付自如。我的问题是关于 CentOS 6.3 x64 系统上的 Yum 更新。
基本上由于某种原因，安装 Murmur（Mumble）后它不允许我更新 - 我感觉这与一个或多个所需的包有关。
这是我运行“yum update”时得到的结果：
yum update
Loaded plugins: fastestmirror, priorities
Loading mirror speeds from cached hostfile
* base: ftp.heanet.ie
* epel: ftp.heanet.ie
* extras: ftp.heanet.ie
* updates: centos.weepeetelecom.nl

Not found
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
现在，根据 Murmur 的安装说明，我可以看到两个熟悉的项目：
1 - perl-devel-5.10.1-136.el6.x86_64：我认为这与 epel-release-6-8.noarch.rpm 有关
2 - db53-devel-5.3.21-1ice.el6.x86_64：可能与此相关，zeroc-ice-el6.repo
我这样做对吗？如果是这样，我该如何解决这个问题？
安装说明如下：
http://mumble.sourceforge.net/Install_CentOS6
- 标题下：新软件包 1.2.4 (x64)
任何帮助都会受到感谢，即使我只是被指引正确的方向。
谢谢大家。

因此我尝试了“Michael Hampton”解决方案，一切都很顺利，直到安装 murmur；我得到的只是以下内容：
yum install murmur
Loaded plugins: fastestmirror, priorities
Loading mirror speeds from cached hostfile
* base: ftp.heanet.ie
* extras: ftp.heanet.ie
* updates: ftp.heanet.ie
Setting up Install Process
No package murmur available.
因此我尝试安装它，并得到以下结果：
rpm -ivh https://www.dropbox.com/s/hs0ztzrdy4unn75/mumble-server-1.2.4-1.el6.i686.rpm

对包裹本身也有同样的投诉。
是不是 YUM 的 murmur 安装没有链接到 CentOS？看来是 Fedora。抱歉，我不知道这里的正确术语。
答案1
您走在正确的轨道上。发生的事情是 zeroc-ice 存储库中有一个软件包 (db53-devel)，它淘汰了基础存储库 (db4-devel) 提供的软件包，但您安装的其他软件包需要这个淘汰的软件包。从长远来看，正确的解决方法是让 zeroc-ice 存储库维护人员更正 db53-devel 的提供标签，以便它也提供 db4-devel 功能。从短期来看，我最好的建议是您在更新期间禁用 zeroc-ice 存储库：yum update --disablerepo=zeroc-ice。
答案2
EPEL 中没有适用于 Centos 6 的 murmur 包。因此删除 zeroc ice 存储库的解决方案是不正确的。
只有当软件包存在于 EPEL 中时，“yum install murmur”才会起作用。要手动安装您下载的 RPM，您需要 zeroc-ice 存储库来获取依赖项。
正如 yum 所建议的，您可以使用 --skip-broken 跳过损坏的依赖关系问题并更新系统上的其他软件包，或者您可以通过在 /etc/yum.repos.d/zeroc-ice-el6.repo 中设置 enabled=0 来禁用存储库。
答案3
您唯一需要做的就是从我的 Centos 上的存储库文件进行编辑，例如在以下路径中：
/etc/yum.repos/Centos-Base
删除所有依赖 zeroc-ice 的存储库行
就这样..
问候！
