E: Unable to locate package cuda-toolkit-8-0

How can I solve it?

Normally JetPack would download this from NVIDIA. Is there anything about your network which might be failing? E.g., a firewall or router issue?

Hi linuxdev,

personally, I think not. I installed Jetpack on other occasions, always using the same computer. the problems started when I installed Java to do other things.
Below the lines code I used to install Java

sudo apt-get purge openjdk*
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

after I lost the Nsight software and cuda package.

I couldn’t say if the Java install is related, but JetPack does use Java and was built around the version native to Ubuntu 14.04/16.04. It seems like a possibility. Can you say more about what you meant that you lost nsight and cuda before (did installing another Java version uninstall packages it didn’t think were compatible)?

Are you able to download via:

wget http://developer.download.nvidia.com/devzone/devcenter/mobile/jetpack_l4t/006/linux-x64/cuda-repo-ubuntu1604-8-0-local_8.0.34-1_amd64.deb

(this is the version for a desktop host)
