不能运行Acon DA的C++环境

Question

我使用^ {CD1>}来设置C++环境。 当我输入jupyter kernelspec list时，一切正常

Available kernels:
  c          /home/UserName/.local/share/jupyter/kernels/c
  python3    /home/UserName/anaconda3/envs/mixed/share/jupyter/kernels/python3
  xcpp11     /home/UserName/anaconda3/envs/mixed/share/jupyter/kernels/xcpp11
  xcpp14     /home/UserName/anaconda3/envs/mixed/share/jupyter/kernels/xcpp14
  xcpp17     /home/UserName/anaconda3/envs/mixed/share/jupyter/kernels/xcpp17

但是在我打开jupyter笔记本并使用C++17创建helloworld.ipynb之后，环境无法加载。以下是输出：

我已经尝试安装gcc，更新conda packges，但它保持不变。 我正在使用Ubuntu20.04LTS
