Я использовал conda install xeus-cling -c conda-forge для настройки среды c .
Когда я ввожу jupyter kernelspec list , все в порядке

 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
  

Но после того, как я открыл свой jupyter notebook и создал helloworld.ipynb с помощью C 17 , среда не может загружаться. Вот результат:

Я попытался установить gcc, обновить пакеты conda, но он остается прежним.
Я использую Ubuntu 20.04 LTS.
