Let#39;s Encrypt在生成证书或者是更新证书会报如下错误：Upgrading certbot-auto 1.12.0 to 1.13.0...Couldn#39;t download https://raw.githubusercontent.com/certbot/certbot/v1.13.0/letsencrypt-auto-source

Let's Encrypt在生成证书或者是更新证书会报如下错误：

Upgrading certbot-auto 1.12.0 to 1.13.0...

Couldn't download https://raw.githubusercontent.com/certbot/certbot/v1.13.0/letsencrypt-auto-source/letsencrypt-auto. <urlopen error timed out>

原因是：certbot-auto将始终尝试从最新版本中获取自身的最新版本。

解决方法：在命令最后加上 --no-self-upgrade 即可。

比如：

certbot-auto renew --no-self-upgrade
