ubuntu can't find serial port

I'm using Ubuntu 18.04.2 LTS downloaded from Microsoft store and Arduino IDE. I'm trying to use ESP32 in Ubuntu, but Ubuntu can't find the serial port.

In Arduino, Tools>Port is greyed out.In Windows, I can see ESP32(COM7) and it works.

lsusb outputs nothing.
dmesg only outputs [0.009121] Microsoft 4.4.0-17763.379-Microsoft 4.4.35.

I tried:

• kernel update
• add the user to dialout
• install cp210x driver
