我正在将 RHL 7.6 升级到 7.7，但遇到了奇怪的错误。
$>uname -r

yum can be configured to try to resolve such errors by temporarily enabling
disabled repos and searching for missing dependencies.
To enable this functionality please set 'notify_only=0' in /etc/yum/pluginconf.d/search-disabled-repos.conf

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

虽然yum check很干净，但yum check-update给我的是：

实际上我检查了一下 /etc/yum.repos.d/redhat.repo……我注意到我缺少“ rhel-7-server-rpms/7Server/x86_64”存储库。添加它后，一切正常。
