update_kernel.sh: ti-sgx-es8-modules not found

[brghena]

I'm trying to update the kernel on a Beaglebone Black and ran into an issue where it is unable to locate the package ti-sgx-es8-modules-4.6.4-bone3. I've included the script output below.

sudo /opt/scripts/tools/update_kernel.sh --beta --bone-channel
