所以，这是因为我正在尝试更新亚马逊EC2服务器上的OpenSSL。但是，当我尝试运行sudo yum update openssl时，我得到：Error: Package: 1:openssl-1.0.1e-37.66.amzn1.x86_64 (amzn-updates)
Requires: libc.so.6(GLIBC_2.14)(64bit)
Error: Package: 1:openssl-1.0.1e-37.66.amzn1.x86_64 (amzn-updates)
Requires: libc.so.6(GLIBC_2.17)(64bit)
Error: Package: 1:openssl-1.0.1e-37.66.amzn1.x86_64 (amzn-updates)
Requires: libc.so.6(GLIBC_2.15)(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我尝试了两个建议命令，但都没有成功：sudo yum update openssl --skip-broken
Packages skipped because of dependency problems:
1:openssl-1.0.1e-37.66.amzn1.x86_64 from amzn-updates
sudo rpm -Va --nofiles --nodigest对没有影响
而且。。。如果我尝试：sudo yum install glibc

Nothing to do
我的其他选择是什么？

看起来可能是几件事。也许你用epel repo安装的东西需要特定版本的glibc，所以它导致你无法安装最新版本。或者您的回购元数据已经过期。有几件事需要尝试。
您可以使用清除回购元数据
sudo yum clean all
然后
sudo yum update openssl
您也可以尝试使用暂时禁用epel回购
sudo yum --disablerepo epel update openssl
如果您不想将glibc作为更新的一部分进行更新，您也可以使用以下命令将openssl升级到根据glibc 2.12编译的版本：
sudo yum --releasever=2013.09 update openssl
