[HELP] "unknown server OS" error on docker_dli_run.sh

I was doing my project so far without a issue on Jetson Nano 2GB in headless setup.
Recently I used an external monitor to test couple of things.
After that I get below error when I run docker on headless setup.
I’m really stuck here and any help would be greatly appreciated.

My docker_dli_run.sh is as follows and I have not changed anything from day1
dileepa@linux:~$ cat ./docker_dli_run.sh
sudo docker run --runtime nvidia -it --rm --network host --volume ~/nvdli-data:/nvdli-nano/data --device /dev/video0 nvcr.io/nvidia/dli/dli-nano-ai:v2.0.1-r32.6.1
dileepa@linux:~$

Hi,

Have you changed any software or library?
Or just connect to a physical display and found this error?

Thanks.

I have not changed any software or library.
Just connected to a physical display and checked how my solution runs.
After that I returned to my usual working setup (headless) and now can’t start the docker…

In the worst case if I have to re-flash, is there a way to backup my project data in the container?
(I have taken a recent backup, but can’t take a risk)

Hi,

Would you mind rebooting the device with the physical display connected to see if it helps?
For backup, you can find some information in the below document:

Thanks.

Thanks for the reply. I tried to reboot boot with a physical display & managed to login to Ubuntu. But issue remained the same and I could not start docker from headless setup.
Finally I re-flashed the SD card and did everything from the scratch.
I still don’t know what caused the issue or how to resolve it without re-flashing.

Hi,

Thanks for the sharing.
It might some issue when switching the headless mode to display mode.

After reflashing, do you get it work correctly?
Thanks.

Thanks for following up.

After re-flashing I managed to get it working correctly.
I have not tried again with external display to check if problem occur again.

Thanks.
