Please try to have a host PC with Ubuntu 20.04 to install the SDK manager, then install it to use the include JetPack 5.0.2 GA to reflash your Jetson Orin devkit.

What do you see for “apt search libgconf-2”? I see this for both Ubuntu 18.04 and Ubuntu 20.04:

libgconf-2-4/bionic,now 3.2.6-4ubuntu1 amd64 [installed]
  GNOME configuration database system (shared libraries)

I use the line usb to type c connected the PC and orin, but the sdk manager not checkout the board like this

Press recovery key then press the power key two seconds and let go…

You can just use lsusb command on your host side instead of letting sdkmanager to detect. If board is in rcm, then it will show nvidia corp device in your lsusb.
