我正在使用此命令启用官方Puppet Labs集合存储库：
当我尝试做的时候：
sudo rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm
错误：
Retrieving http://yum.puppetlabs.com/puppetlabs-release-el-7.noarch.rpm
warning: /var/tmp/rpm-tmp.4CilbA: Header V4 RSA/SHA1 Signature, key ID 4bd6ec30: NOKEY
Preparing... ################################# [100%]
file /etc/yum.repos.d/puppetlabs.repo from install of puppetlabs-release-7-12.noarch conflicts with file from package puppetlabs-release-6-12.noarch
有谁知道如何解决这个问题？
