I tryed to install Jetpack 4.0 EA again, because I could not do completely.
But, JetPack 4.0 Components Manager does not display any packages.
So, I can not move on to the next step.
Jetpack.log is shown below.
10-01 15:35:03.5 N: GoogleAnalytics enabled
10-01 15:35:03.5 E: fopen failed with file local.db, errno = 2
10-01 15:35:03.6 W: Net Exception: Network is unreachable
10-01 16:05:23.0 W: Net Exception: Network is unreachable
I think that network settings are not wrong, because I booted L4T in Xavier in first install.
We’re rolling out the new JetPack 4.1 DP release, your issue is related to that as JetPack 4.0 will not be able to be selected anymore from Components Manager.
Please wait our official announcement for JetPack 4.1 DP release.
