Как запустить установку petalinux в Ubuntu 20.04

Я не могу запустить установку petalinux в Ubuntu 20.04.

abc@alpha:/scratch2/abc/Xilinx$ /petalinux-v2021.1-final-installer.run /scratch2/abc/Xilinx/Petalinux

Это происходит с этой ошибкой.

-bash: /usr/bin/python: No such file or directory

Я редактирую свой вопрос с помощью терминала. Я не уверен, что делаю не так.
