【问题描述】：

我想在 Amazon Linux 上安装最新升级的 certbot 版本。

Certbot 已更新其发行版，该发行版未使用 Amazon Linux AMI 2016.03.3.x86_64 HVM GP2 升级。

当我尝试使用 yum update -y 更新 Linux 时出现以下错误

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

是否需要升级 Amazon Linux？

【问题讨论】：

标签： nginx amazon certbot

【解决方案1】：

是的，我必须将 AWS Linux AMI 2016 迁移到 AWS AMI 2 才能升级 certbot 版本。

我遵循以下步骤：

sudo amazon-linux-extras install epel -y sudo yum-config-manager --enable epel sudo yum update -y sudo yum install -y certbot python2-certbot-nginx sudo certbot -v

已安装 certbot 1.11。
