I can't install and use perf tool on my linux server:

Linux vzu01-ubuntu 3.16.0-30-generic #40~14.04.1-Ubuntu SMP Thu Jan 15 17:43:14 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

root@vzu01-ubuntu:~# apt-get install linux-tools

Package linux-tools is a virtual package provided by:

  linux-tools-generic-lts-saucy 3.13.0.57.64
  linux-tools-generic 3.13.0.57.64
You should explicitly select one to install.

E: Package 'linux-tools' has no installation candidate

I tried installing different packages but it wouldn't let me use perf anyway... Could it be anything wrong with repository list?

  • Many years later, but I am experiencing the same frustration, that the mainline kernel PPA does not include the tools and cloud-tools packages. :(

  • @mikepurvis this particular question shouldn't have appeared if it was today. These days my needs are covered by apt install linux-tools-common

  • linux-tools-common is just the manpages and some pass-thru wrapper scripts, even in eoan. You still need the linux-tools package compiled for your specific kernel, which only seems to be available for the the supported kernels, not the mainline ones.

You can install linux-tools this way.

sudo apt-get install linux-tools-generic-lts-utopic

But it looks that you never updated your system. Kernel is outdated. Run

sudo apt-get update && sudo apt-get dist-upgrade

That will get your kernel and other software up to date. Versions of linux-image and linux-tools will match after reboot.

  • this was done. It's not a question of how to install, it's the question what to install. The versions MUST coincide and they don't: root@vzu01-ubuntu:~# perf WARNING: perf not found for kernel 3.16.0-30 You may need to install the following packages for this specific kernel: linux-tools-3.16.0-30-generic linux-cloud-tools-3.16.0-30-generic You may also want to install one of the following packages to keep up to date: linux-tools-generic-lts-<series> linux-cloud-tools-generic-lts-<series> root@vzu01-ubuntu:~#

  • well, I install the system from a scratch 2 months ago. It was the latest stable release. update and dist-upgrade were just done as you advised. The kernel version is still 3.16.0-30 and perf from linux-tools-generic-lts-utopic does not match!

  • Did you reboot?

  • And it is not a good idea not to update the system.
