Is it a custom carrier board or devkit?
Which JetPack version you want to install?
Are you on VM or native Ubuntu 18.04 host PC?

i have a jetson nano developer kit. I tried to do this using a separate computer with Ubuntu 18.04.6 lts installed i think the last version i tried to install jetpack was 4.6.2v i did the installation with sdkmaganer i followed the process sequentially

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

But your previous desctiption said you’re flash with TX2?
Which one is correct?
