我在Ubuntu 18.04 LTS VPS上设置juju bootstrap localhost时遇到问题。我已经在另一台机器上完成了相同的配置，并且效果很好。
我的VPS信息是 94 GB RAM 和 480 GB SSD RAID 5
在我update和upgrade的VPS之后，我遵循迷人的kubernetes 文档中的命令：
sudo apt purge liblxc1 lxcfs lxd lxd-client
sudo snap install lxd
lxd init --auto
lxc network set lxdbr0 ipv6.address none
sudo swapoff -a
sudo usermod -a -G lxd $USER
注销并再次登录！
sudo snap install juju --classic
juju bootstrap localhost
此后，juju开始设置本地主机：

我不知道女巫是不是我做错了，或者这是一个bug还是什么，希望你们能帮助我，谢谢。
