Sorry to keep you waiting for the upgrade - as discussed above, updating JetPack to Ubuntu 20.04 also requires an update to Linux kernel 5.x. This is a massive undertaking to apply/verify all of the changes needed to support the Tegra devices. As discussed above with @gtj, we are working to mitigate this migration effort needed for future updates.
