启动失败:远程“管理器”未知或无法到达-多通返回退出代码2

Question

我正在学习如何通过跟踪Ubuntu网站教程创建快照。前三步走得很好，但就在我要走到第四步的时候，我需要去一个地方。第二天，我试着继续下去，但什么也没成功。

当我试图运行snapcraft时

❯ snapcraft -v
Starting Snapcraft 7.3.1

Launching a VM.

An error occurred with the instance when trying to launch with 'multipass': returned exit code 2.
Ensure that 'multipass' is setup correctly and try again.

当我检查多通的内容时，它显示了大量的网络访问被禁用，即

❯ snap logs multipass

我不确定这些日志是否真的是相关的，如教程中所说的使用core18 (我曾经使用过)，我也尝试使用core20。

解决方案是使用以下方法重新启动多通道抢断

> sudo snap restart multipass
