20.04 ubuntu support added into sdkmanager?

finally added?
so jetson could be flashed from 20.04 ubuntu?
could you confirm that it is applicable to Jetsons flashing, not only Drive etc?

For SDK manager itself, the Ubuntu 20.04 is supported.
However, for JetPack, it can only support the Ubuntu 18.04 for now.

So the flashing process could start with sdkmanager from ubuntu 20.04, but the jetson will be with 18.04 Os, or you mean that sdkmanager will run on 20.04 ubuntu but it won’t flash the Jetson because of the Jetpack?

@kayccc if you meant the former - too bad; you should explicitly pointed it out to save developers time, IMHO.

switching/ falling back to docker sdkmanager option which seems to fail though

trying to address the latter with

sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils

unfortunately it did not work

flash.sh will neither work on 20.04?
UPD seems the cause was missed binutils package at Host OS
But it still doesn’t resolve the issue
UPD after kind of again installing qemu static seems the issue got passed

For Jetson/JetPack, that’s Ubuntu 18.04 now.
The SDK Manager is for all NVIDIA product, not just Jetson/JetPack, some descriptions is put under system requirement table at SDK manager wed page - “For specific DRIVE, JetPack, Clara AGX, Rivermax, DOCA and Ethernet Switch deployed SDKs, see product release notes.”

how about initrd flashing from 20.04? Not supported? the only chance is to approach the slippery slope of sdkmanager docker implementation for flashing from 20.04? is it possible to flash with initrd method a custom syste,img or system.raw.img? both? neither of the two?

I can’t tell it can work or not, but you can refer to below thread: Flash AGX Xavier from Ubuntu 20.04, errors? - Jetson & Embedded Systems / Jetson AGX Xavier - NVIDIA Developer Forums

by experiment I was able to find out that nvmflash.sh supports ubuntu 20,04
