Essentially I would like to perform the following install
sudo apt install linux-headers-$(uname -r)
However, it throws up the error
E: Unable to locate package linux-headers-4.9.140-tegra
E: Couldn’t find any package by glob ‘linux-headers-4.9.140-tegra’
E: Couldn’t find any package by regex ‘linux-headers-4.9.140-tegra’
I found bits and pieces where people downloaded the source_sync.sh and run, but I have been unable to find a guide or walkthrough of the process.
If someone can provide a walkthrough, or even just point me to the documentation that I should be reading, that would be greatly appreciated.
