Hi:
after executing “sudo apt-get install linux-tools-common” and type “perf”

what steps I shall take to complete the installation ?!
ycw@ycw-desktop:~$ perf
WARNING: perf not found for kernel 4.9.140
You may need to install the following packages for this specific kernel:
linux-tools-4.9.140-tegra
linux-cloud-tools-4.9.140-tegra
You may also want to install one of the following packages to keep up to date:
linux-tools-tegra
linux-cloud-tools-tegra
ycw@ycw-desktop:~$ sudo apt-get install linux-tools-4.9.140-tegra

There is no repository installed by default that contains those packages.
