Erro ao instalar o Pycharm

Estou tentando instalar o Pycharm no Debian 10 e apresenta a seguinte msg abaixo:

root@debian:/home/brunitus/Downloads/Documents/Pycharm/pycharm-community-2020.1.3# ./bin/pycharm.sh
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

Startup Error: Unable to detect graphics environment

Alguém sabe o que pode ser?

Por que tás rodando o pycharm como root?
