I am working with an NVidia Jetson. The Ubuntu software update crashed, and now as I fear the system will not boot properly.

The way the system is configured, a command prompt flashes for an instant before an NVidia graphic comes up and normally the Ubuntu GUI follows.

Someone suggested holding shift during boot, but this did nothing.

I was able to get to the command line using Ctrl+Alt+F1.

Then, I was able to follow one user's instructions on this thread. It was not necessary to recover the system from USB.

In your /home/ubuntu/ folder there will be a folder NVIDIA-INSTALLER containing the release. Go to this directory and extract it.

sudo -i
tar xvjf Tegra124_Linux_R19.3.0_armhf.tbz2

Do the following to change the LDK ROOTFS DIR (not sure what that is, but this works ...)

export LDK_ROOTFS_DIR=/
echo ${LDK_ROOTFS_DIR}

Go to the Linux For Tegra directory and run this script:

cd Linux_for_Tegra
./apply_binaries.sh

Confirm your success (I got all OK's):

sha1sum -c /etc/nv_tegra_release

On sudo reboot my GUI loaded after a slightly longer than normal black screen (for suspense obviously).
