I don’t know what you are asking about.  
Can you please elaborate more?

I’m using the R35.3.1 version. The system is ubuntu20.04. The python version of the system is 3.8.5. How do I solve the following problems?

`tegrasign_v3_util.py` is still Python 2, so you also need to have Python 2 installed.

I installed the python2  
Use the command:`sudo apt install python2`  
. But the error is the same as before.

That’s because **python** on your system is still linked to Python 3.  
Change the link to Python 2 or add the shebang in ` tegrasign_v3_util.py`:

```auto

你有run過`sudo ./tools/l4t_flash_prerequisites.sh`嗎  
理論上需要的package裝完之後不應該有這樣的錯誤

我的環境是這樣
