install jetpak 3.1 failed , in TX1 / TX2, Very worry Very worry
JetPack should not be run as root, this causes problems. JetPack does ask for a password when doing things needing sudo…but initial startup should not use root. If in doubt of file permissions you may want to delete the JetPack install location and run it again as non-root.
One thing I wonder is if there is a lock file still in place which is now owned by root (due to the previous run as root), but not expected to require root permissions to delete. Have you tried deleting the JetPack directory and re-installing it? I would actually suggest to download a fresh copy of JetPack itself as well. If this fails, then you can probably narrow down cause to networking.
Please download JetPack3.1 again.
chmod +x JetPack-L4T-3.1-linux-x64.run ./JetPack-L4T-3.1-linux-x64.run
thank you very much. Have solve this problem.
