我想使用 snap 安装 certbot，但是当我尝试官方说明：
sudo snap install core; sudo snap refresh core
sudo snap install --classic certbot
但返回：
错误：无法执行以下任务：
- 如果存在，则运行“certbot”快照的配置钩子（运行钩子“配置”：/var/lib 非 root 拥有的 1000:1000）
之前，我使用以下命令卸载了 certbot（来自 apt）：
sudo apt-get remove -y certbot python3-certbot-apache
发生了什么？我正在使用 Ubuntu 18.04 Bionic
从错误来看，我需要将所有者更改/var/lib为 root 用户。但我更改后仍然出现相同的错误。我应该递归地将文件夹更改为 root 吗？
以下ls是 /var/lib：

答案1
我只需要/var/lib/snapd使用以下命令将文件夹更改为 root 用户：
chown root:root -R /var/lib/snapd/
在其他服务器上，/var/lib文件夹和里面的内容都是 root 拥有的。我不清楚为什么这台服务器上的文件夹用户不是 root，更改后我现在可以安装 certbot 并使用它。
