Letsencrypt证书升级问题

Question

在Ubuntu 16.04.2 LTS上，我正在尝试使用./ letsencrypt auto renew -dry-run升级letsencrypt证书，并给出了下面的错误

Error: couldn't get currently installed version for /root/.local/share/letsencrypt/bin/letsencrypt: 
Traceback (most recent call last):
  File "/root/.local/share/letsencrypt/bin/letsencrypt", line 7, in <module>

ImportError: No module named datetime

你能帮帮忙吗

Answer 1

只管去做

rm -rf /root/.local/share/letsencrypt/bin/letsencrypt

再试一次。

Answer 2

我通过删除virtualenv bin目录并重新运行certbot-auto命令解决了这个问题，这将导致certbot重新安装依赖项。要查找目录的位置，请查看错误响应的第一行：Error: couldn't get currently installed version for /root/.local/share/letsencrypt/bin/letsencrypt。这个位置会有所不同。

相应地，删除/root/.local/share/letsencrypt/bin/应该会删除已安装的依赖项，并获得证书，但该证书已启动并运行。

Answer 3

这对我很有效(Linux Debian 3.16.64-2)：

mv /opt/eff.org/certbot /opt/eff.org/certbot.old

certbot-auto
