Revert back to version Ubuntu 18 instead Ubuntu 20

Updated to 20 ubuntu by mistake.
The UI doesn’t start.
I want to erase all data and go back to Ubuntu 18.

Flash your board with sdkmanager.

How to do it?

Didn’t you do that in the first time you used your AGX?

JetPack manager on host only about nvidia soft? But where is Ubuntu reset?

How to clear all the memory? I want to reset to factory settings. So that the device is out of the box

No, sdkmanger also includes to reflash the whole system…


Twice a failure.

The “Jetson SDK Components” does not matter in this issue. You can skip that at this moment.

Please just try that “Flash jetson OS”. If it has error, please press that"EXPORT LOGS" button and attach the full log here.

“Flash jetson OS” - successfully, but nothing happened. Still Ubuntu 20.

Please share two logs

  1. EXPORT LOGS from sdkmanager.

  2. Use below method to dump the serial console log.

Are you sure the sdkmanager GUI told you that the flash is finished with success?

This time the process ended unsuccessfully.

Please also share log. It is not possible to help you just with one comment “ended unsuccessfully”.

Also, is your ubuntu host a VM?

My host is Virtual Box Ubuntu 18.04 on MacBook Pro.
SDK Manager log pinned as zip file here - Revert back to version Ubuntu 18 instead Ubuntu 20 - #12 by user23343

SDKM does not support VM or VB. Please try with native ubuntu 18.04 host.
