OpenVZ vps 使用 snapd 部署 certbot

在 OpenVZ 的 vps 上使用 snapd 时, 会出现如下提示

error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:
       /tmp/sanity-mountpoint-404380626: mount failed: Operation not permitted.
error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:
       /tmp/sanity-mountpoint-404380626: mount failed: Operation not permitted.

下面介绍解决办法:

sudo apt install fuse squashfuse snapd
sudo mknod -m 666 /dev/fuse c 10 229
sudo snap install core; sudo snap refresh core
sudo apt-get remove certbot
sudo snap install --classic certbot
sudo ln -s /snap/bin/certbot /usr/bin/certbot
