How To Install Linux Perf Tools on Ubuntu 20.04 LTS with WSL2

Ubuntu 20

In this article, we will walk you through the process of installing the Linux Performance Tools (perf) on Ubuntu 20.04 LTS using Windows Subsystem for Linux 2 (WSL2).

Introduction

The perf tool is a powerful utility for performance analysis in Linux. It provides a wide range of functionalities to measure and analyze system and applications performance. However, installing perf on Ubuntu 20.04 LTS running on WSL2 can be a bit tricky due to certain kernel version mismatches. This guide will help you overcome these issues and get perf running smoothly on your system.

Prerequisites

Before we begin, make sure you have the following:

  • A system running Windows 10 with WSL2 enabled.
  • Ubuntu 20.04 LTS installed on WSL2.
  • Sudo or root access to the Ubuntu system.

Step 1: Update Your Ubuntu Installation

First, it’s good practice to ensure your Ubuntu installation is up-to-date. You can do this by running the following commands:

sudo apt update
sudo apt upgrade

The sudo apt update command updates the package lists for upgrades for packages that need upgrading, as well as new packages that have just come to the repositories. The sudo apt upgrade command will then upgrade all currently installed packages.

Step 2: Install Necessary Packages

Next, install the necessary linux-tools-generic and linux-cloud-tools-generic packages using the following command:

sudo apt install linux-tools-generic linux-cloud-tools-generic

These packages provide generic files for linux-tools and linux-cloud-tools.

Step 3: Check the Installed Kernel Version

To download the correct kernel headers, you need to know your installed kernel version. You can check this by running:

uname -r

The uname -r command will display your current kernel version.

Step 4: Download the Corresponding Kernel Headers

Once you have your kernel version, download the corresponding kernel headers from the official Ubuntu website. For example, if your kernel version is 5.4.72-microsoft, you can download the headers using the following command:

wget https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.72/linux-headers-5.4.72-microsoft-standard_5.4.72-microsoft-standard-1_amd64.deb

The wget command is a free utility for non-interactive download of files from the web.

Step 5: Install the Downloaded Kernel Headers

After downloading the kernel headers, install them using the following command:

sudo dpkg -i linux-headers-5.4.72-microsoft-standard_5.4.72-microsoft-standard-1_amd64.deb

The dpkg -i command is used to install a downloaded Debian (.deb) package.

Step 6: Install Perf

Now, you can install perf using the following command:

sudo apt install perf

The sudo apt install perf command will install the perf tool.

Step 7: Verify the Installation

Finally, verify the installation by checking the version of perf:

perf --version

If perf is installed correctly, this command will display the version of perf.

Conclusion

You have now successfully installed the Linux Performance Tools (perf) on Ubuntu 20.04 LTS using WSL2. Remember, WSL2 has limitations with hardware counters, so the results obtained from perf may not be as expected. For more information and alternative solutions, you can refer to the Stack Overflow post discussing this topic.
