我正在尝试在 Hyper-V 中的 Ubuntu 18.04 VM 上安装 The Littlest JupyterHub。

我在 Hyper-V 中创建了一个外部（桥接）网络，以便我可以从同一网络上的笔记本电脑访问它。我想测试 JupyterHub 处理断开的网络连接的能力。

我认为安装程序在尝试升级版本时失败，conda但日志不是很清楚。我做错了什么，还是有安装程序错误？

multipass launch bionic --name jupyterhub --cpus 2 --mem 3G --network "name=HyperV External Switch"
multipass shell jupyterhub

sudo apt update
sudo apt install python3-venv python3-dev python3-pip git curl
curl -L https://tljh.jupyter.org/bootstrap.py | sudo -E python3 - --admin jhadmin

ubuntu@jupyterhub:~$ curl -L https://tljh.jupyter.org/bootstrap.py | sudo -E python3 - --admin jhadmin
