Don't let L4T SDK break your ubuntu


L4T uninstalled my opencv and replaced it with opencv4tegra, which would cause trouble when run system upgrade. Here are some simple command line to uninstall it.

Remove L4T using its uninstall tool

Go to your L4T installer folder and run

sudo ./JetPack_Uninstaller

Select all of them then wait program done.

Remove L4T dependencies

dpkg --get-selections | grep :i386 | awk '{print $1}'

apt-get remove --purge $( dpkg --get-selections | grep :i386 | awk '{print $1}' )
And then retry the

dpkg --remove-architecture i386
