  9. Please describe the issue in detail.

    • failed to set dtr/rts, couldn't enter turtlebot@turtlebot, still stays in ubuntu directory
    • I've tried solution in #738: $ sudo apt-get purge modemmanager, also tried uploading with the recovery mode
    • neither worked. the robot worked when I tested by Press and hold PUSH SW 1 /2 But when I try to connect turtlebot from my PC, failed. not sure if this has something to do with the error of failed to set dtr/rts

I use ubuntu through VirtualBox in my PC, the network connection works well. IP of turtlebot is 172.20.10.xx PC IP (Virtualbox) is 172.20.10.yy

I also tried to connect turtlebot3 from my pc, but after $ ssh ubuntu@ 172.20.10.xx and input password: turtlebot

it returns error: permission denied (publickey, password) or connection closed by 172.20.10.xx port 22 there is eduroam wifi in my room, but I didn't use that. I used the private wifi through my phone hotspot. What reason could it be?

Hi @laila-fangyan Have you also tried setting up the USB port as below?

$ rosrun turtlebot3_bringup create_udev_rules

The OpenCR firmware download is successfully completed, but connecting to TurtleBot3 from the PC isn't related to this issue. Virtual computing environment is not recommended as there could be various configurations that could interrupt ROS connection.

When connecting ssh, make sure that there isn't a space between @ and the IP address as below.

$ ssh ubuntu@172.20.10.xx

Hi @ROBOTIS-Will

Thanks for the instruction. Do you mean the OpenCR setting up is completed? I can just ignore "failed to set dtr/rts"? Does it matter that it stays in ubuntu@ubuntu directory, not enters turtlebot@turtlebot after $ ./update.sh $OPENCR_PORT $OPENCR_MODEL.opencr"?

I just tried $ rosrun turtlebot3_bringup create_udev_rules in my PC, still returns "permission denied".

Thanks Fang

@laila-fangyan Have you also tried replacing the micro USB cable?

Seems like you don't have permission to run the script. I've recovered RPi3B+ using the Noetic image file in the eManual and ran the command which resulted as below. image

Hi @laila-fangyan is this error solved cdc_acm 1-1.2:1.0: failed to set dtr/rts?

Hi, I gave up to install through VM. I started over the installation under single Ubunbu OS. And no such issue any more.

@laila-fangyan I see, thank you for the reply.
