I'm currently working on Raspberry pi zero. When i write:

sudo apt-get install linux-perf

@Saiprasant its not advisable to do rpi-update; its mentioned in a lot of blogs. Thats why I skipped this part. – Matti

Answer 1

I encountered the same problem in the k8s pod environment.

Install perf in Debian GNU/Linux 10:

sudo apt install linux-perf

Tried to use perf, but reported an error:

:~/perf-tools$ sudo perf -h
/usr/bin/perf: line 13: exec: perf_5.4: not found
E: linux-perf-5.4 is not installed.

After research, I found that /usr/bin/perf used uname -r to get the linux kernel version of the host instead of the version of the container.

So I solved it by renaming it.

sudo cp /usr/bin/perf_4.19 /usr/bin/perf_5.4

I am using the Debian 11:

# cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

My linux kernel version is:

# uname -r
6.3.3

perf_5.10 is already installed:

# dpkg -l linux-perf
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name           Version      Architecture Description
+++-==============-============-============-===================================================
ii  linux-perf     5.10.191-1   amd64        Performance analysis tools for Linux (meta-package)

But while running the perf command, I was getting the following error:

# perf top --sort cpu,comm,dso
/usr/bin/perf: line 13: exec: perf_6.3: not found
E: linux-perf-6.3 is not installed.

So, I copied the existing file to the /usr/bin/perf_6.3:

# cp /usr/bin/perf_5.10 /usr/bin/perf_6.3

Now perf command started working as expected.

I was running the following in a Docker container of Debian Buster, version 10. It works now.

apt install linux-perf
cd /usr/bin/
ls -l # Find out the installed version of perf, for example: perf_4.19
 perf #  Find out the required version of perf, for example: perf_6.1
cp perf_4.19 perf_6.1
perf -h # To check if everything is working.
