I am getting an error while running apt-get update on both my nvidia jetson tk2 and host computer.
I am getting the following error:
Ign:13 file:/var/libopencv4tegra-repo Release.gpg
Reading package lists… Done
W: Invalid ‘Date’ entry in Release file /var/lib/apt/lists/_var_nv-gie-repo-ga-cuda8.0-gie1.0-20170116_Release
W: GPG error: file:/var/libopencv4tegra-repo Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY D88C3D385C37D3BE
W: The repository ‘file:/var/libopencv4tegra-repo Release’ is not signed.
N: Data from such a repository can’t be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
W: Invalid ‘Date’ entry in Release file /var/lib/apt/lists/_var_libopencv4tegra-repo_Release
Which has effectively blocked me from developing on my host computer as well.
Any ideas/recomendations/help would be greatly appreciated.
Almost one year later there is still no solution from you guys?..
Ran into the same problem:

The only workaround I could find was - to remove this misconfigured repo completely from apt (adding the key manually doesn’t work as it’s not registered by Nvidia)…
When do you expect it to be fixed finally? In Jetpack 3.2?
We mentioned it at release notes as below, and it’s only a warning message and doesn’t affect the functionality of subsequent “apt-get update”: The public key to verify the OpenCV4Tegra dpkg-format package is not provided, so warning messages will be seen during installation and during subsequent package management updates.
