今天从官方网站下载 tidb-docker-compose出现了如下报错：
[root@foundation38 docker]# git clone https://github.com/pingcap/tidb-docker-compose.git
Cloning into 'tidb-docker-compose'...
fatal: unable to access 'https://github.com/pingcap/tidb-docker-compose.git/': Peer reports incompatible or unsupported protocol version. 失败原因是版本问题
[root@foundation38 docker]# yum update nss curl yum update nss curl 更新版本
[root@foundation38 docker]# git clone https://github.com/pingcap/tidb-docker-compose.git 可以正常下载
