I already submitted the query below to the CUDA setup and install section. But I wasn’t getting any reply and I was told that I should re-post in Embedded systems:
I recently bought the Jetson TK1 board and I managed to install CUDA6.5 on it to do native compilation. However, I also want to do cross compilation. To that end, I am trying to do a cross-build installation on my Ubuntu 14.04 x86 64 bit host machine. More precisely, I am trying to perform the cross-build installation on a Ubuntu guest virtualbox I have running on my Windows host.
I would like to add that the GPU on my host machine is not CUDA capable. But I don’t think this matters because I only intend to compile CUDA programs on the host machine, not run them.
The steps I am following are in section 5.1 of the CUDA setup and installation guide: https://devtalk.nvidia.com/default/topic/803524/embedded-systems/anyone-have-a-guide-for-cloning-jetson-tk1-without-the-jetpack-development-pack-/
When I try to run sudo dpkg -i cuda-repo-ubuntu1404_6.5-14_amd64.deb, I get the following error:
auggy@auggy-VirtualBox:~/Downloads$ sudo dpkg -i cuda-repo-ubuntu1404_6.5-14_amd64.deb

gpg: no valid OpenPGP data found.
Failed to add GPGKEY at http://cuda-repo/repos/GPGKEY to apt keys.
I am pretty sure I am using the correct operating system:
auggy@auggy-VirtualBox:~/Downloads$ uname -m && cat /etc/*release
DISTRIB_DESCRIPTION=“Ubuntu 14.04.2 LTS”
VERSION=“14.04.2 LTS, Trusty Tahr”
PRETTY_NAME=“Ubuntu 14.04.2 LTS”
I would really appreciate some help on this issue. I am fairly new to Ubuntu so please bear with me.
