Juju命令失败-错误无法打开/ tmp / juju-store-lock-3635383939333230

问题描述

我对Juju有点问题，如果有人遇到它或者知道它可能是什么，我就感到不安。

我正在将Juju 2.8.1-focal-amd64与MAAS 2.8.1（8567-g.c4825ca06）结合使用，以部署Openstack云。

我已经以root用户身份安装并运行Juju命令。

当我输入Juju命令时，收到以下消息： 错误无法获取锁定文件以获取当前控制器名称：无法打开/ tmp / juju-store-lock-3635383939333230：权限被拒绝

当我尝试引导控制器时，它首先出现：

我已尝试更改此文件的权限（使用chmod 777），但这不起作用。

预先感谢：）

解决方法

发生这种情况是因为 Juju 希望以普通用户而不是 root 身份使用 juju 命令。从 /tmp/juju-store-lock* 中删除本地文件并重试应该可以解决此问题。

顺便说一句，juju 使用原始用户执行 try and chown the permissions 锁定文件，但似乎这并不总是完美的。
