Using the SDK manager (2.1.0) on Ubuntu 24.04, installing Jetpack 6.1 fails to flash to Orin.
For future seekers, the “fix” I’ve found is to change both “/etc/os-release” and “/etc/lsb-release” temporarly to “fool” the SDK manager into thinking it’s running Ubuntu 22.04, so that it correctly pulls packages from the jammy repos instead of noble.
