Gnss | Open device /dev/ttyS0 failed, error: Permission denied

[yooyo-Q]

System information

• Ubuntu 20.04:
• Apollo installed from docker:
• Apollo version (9.0):

Steps to reproduce the issue:

cyber_launch start modules/drivers/gnss/launch/gnss.launch

output:

"Execute chmod 777 /dev/ttyS0"

"When I change the permissions of /dev/ttyS0 to 777, the device can be read correctly. However, every time I restart the server, the permissions revert back to their original state, requiring me to reconfigure them. I would like to know if this is a feature of Apollo or a bug."
