I have used conda install xeus-cling -c conda-forge to setup the c++ environment.
When I input jupyter kernelspec list it's OK
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
But after I opened my jupyter notebook and create a helloworld.ipynb using C++17, the environment cannot load. Here's the output:

I have tried to install gcc, update conda packges, but it stays the same. I'm using Ubuntu 20.04 LTS.
