无法使用snap返回安装certbot :如果存在，运行"certbot“的配置钩子

Question

我想使用snap安装certbot，但是当我尝试官方指令时：

sudo snap install core; sudo snap refresh core
sudo snap install --classic certbot

但返回：

错误:无法执行下列任务：

• 运行"certbot“snap的配置钩子(运行钩子”配置“：/var/lib，而不是根拥有的1000:1000)

以前，我使用以下命令卸载certbot(从apt)：

sudo apt-get remove -y certbot python3-certbot-apache

发生了什么？我用的是Bionic 18.04仿生

从错误中看，我需要将/var/lib的所有者更改为root用户。但我改变了，仍然犯了同样的错误。我应该递归地更改为根到那个文件夹吗？

下面是ls to /var/lib：

Answer 1

我只需要使用下面的命令将/var/lib/snapd文件夹更改为根用户：

chown root:root -R /var/lib/snapd/

在其他服务器中，/var/lib文件夹和内部由root拥有。我不知道为什么这个服务器上的文件夹的用户不是root用户，更改后我现在可以安装certbot并使用它了。
