JetPack-L4T-3.1 installation failed

Hi All,

My host pc : ubuntu 14.04 (64-bits)

I meeting a problem when I installing the JetPack-L4T-3.1.

I downloaded the JetPack-L4T-3.1 at Jetson Download Center Archive | NVIDIA Developer
And follow the below installing steps:
NVIDIA JetPack Documentation

When I ran step 6, the window was empty then I checked JetPack.log in the installer’s folder. It showed the error message “fopen failed with file local.db, errno = 2”

Then I disabled the firewall and tried to use the proxy to solve this issue.
But it showed the same error message.

My colleague successfully installed and ran it before. But he ran it again on his PC this morning, it didn’t work too.

Please give me some advices. Thanks,
