Ubuntu 18.04 Kernel (5.0.13) cpupower does not run

  • 772

I am using the Lenovo Thinkpad e490. I installed dual-boot with Windows, but I had a couple of issues so I updated my Kernel to 5.0.13 (I read in a forum that this version fixes some problems, but newer versions are probably fine too). Now I did some speed test and realized that my CPU is slower then it should be. So I tried to set the CPU governor to performance using cpupower. But somehow it isn't installed. When I type cpupower in the terminal i get:

WARNING: cpupower not found for kernel 5.0.13-050013

You may need to install the following packages for this specific kernel:
    linux-tools-5.0.13-050013-generic
    linux-cloud-tools-5.0.13-050013-generic

  You may also want to install one of the following packages to keep up to date:
    linux-tools-generic
    linux-cloud-tools-generic

All of these packages mentioned are not found when I try to install them with sudo apt-get install <packagename>.

When I run sudo apt-get install cpupower I get:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package cpupower

Is there another way to change the CPU governor and is cpupower really not supported for all kernels?

I also tried several other kernels with the same problem.

  1. I am not sure if this could help, but I had the same message when installing cpupower E: Unable to locate package cpupower I ve read on ubuntu packages site that its requirement was linux-tools-generic, so I successfully installed it. However upon starting it I had that message above it needed it for a different kernel, so I also installed the listed suggestion for my kernel linux-tools-5.0.13-050013-generic. So maybe first installing a generic library linux-tools-generic helped to propel the installation forward with a more specific kernel package, unless you also miss some repositories configurations and libraries in them. I have added Bionic repos to my fossa repos, though I still experience many issues locating various packages as I have installed a slim version of ubuntu if that could be the case perhaps.

  2. Try to install linux-tools for your core name.

    sudo apt-get install -y linux-tools-common linux-tools-$(uname -r)

    Or run

    uname -r

    it returns (for example) 5.11.0-44-generic And you install your version

    sudo apt-get install -y linux-tools-5.11.0-44-generic
