I stupidly upgraded the jetson to ubuntu 20.04 and now am in a broken state. The SDK manager reports no targets for 20.04 to add salt to the wounds there are no options under repair/uninstall. Any ideas on how to get me back to the original factory setup? Thanks.
If you have something valuable on it, then you can clone it for later use. However, generally speaking, your only option would be to flash again. Versions of JetPack/SDKM are listed here:
https://developer.nvidia.com/embedded/jetpack-archive
(documents come with that)
- The utility file ‘flash.sh’ does not appear anywhere on my host system. The documentation for flashing does not indicate where you acquire the flash.sh script and the binaries behind it.
- When I attempt to flash the jetson with the SDKmanager these are the results I get:
$ sdkmanager --cli install --product Jetson --version 4.5.1 --targetos Linux --host --flash all
Authenticating with NVIDIA server…
Login succeeded.
Loading user information…
User information loaded successfully.
Loading server data…
Server data loaded successfully.
-* Available on ubuntu1604, ubuntu1804. For available versions run sdkmanager --query.
I appreciate any help you can offer
So figured out how to install the flash, but it is erroring out, any ideas?

Thanks again
I resolved this by installing 18.04 LTS on my host system. Not sure why the host system has to be the same flavor of OS as the target system but at least I can move on. Thanks for your help.
