如何解决Host-c VPS安装Swizzin后无法安装Let's Encrypt的问题 之前安装不上就比较麻烦，没有证书每次登录都要输入密码，所以再试试。

Please consult the above and/or check the log (less -R +G /root/logs/swizzin.log)查看log
less -R +G /root/logs/swizzin.log)查看日志发现acme.sh安装不成功，主要还需要缺少依赖，让我尝试安装cron, crontab, crontabs，所以acme.sh脚本也没有成功安装到预期的位置。
[Sat Jul 13 08:31:49 UTC 2024] It is recommended to install crontab first. try to install 'cron, crontab, crontabs or vixie-cron'.

/usr/local/bin/swizzin/install/letsencrypt.sh: line 136: /root/.acme.sh/acme.sh: No such file or directory解决步骤
更新系统并安装依赖
sudo apt update
sudo apt install curl cron socat -y手动安装acme.sh
curl https://get.acme.sh | sh -s email=xxx@xxx.com替换 xxx@xxx.com 为您的实际邮箱地址。
检查acme.sh安装成功:
~/.acme.sh/acme.sh --version能查到版本，重新安装Let’s Encrypt:
sudo box install letsencrypt查看后台截图安装成功
显示安装成功，后面就很方便的输入域名访问了。
