Estou ligado

Ubuntu 22.04.5 LTS (GNU/Linux 6.8.0-45-generic x86_64)

Eu instalei os pacotes perf

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

mas quando tento executar perf traceele reclama que o subcomando não está disponível

akhil@akhil-Inspiron-5559:~$ perf trace
perf: 'trace' is not a perf-command. See 'perf --help'.
akhil@akhil-Inspiron-5559:~$ sudo perf trace
[sudo] password for akhil:
perf: 'trace' is not a perf-command. See 'perf --help'.

no entanto, acho que ele está instalado porque quando executo, man perf tracerecebo a página do manual

PERF-TRACE(1)                                                                     perf Manual                                                                    PERF-TRACE(1)

NAME
       perf-trace - strace inspired tool

SYNOPSIS
       perf trace
       perf trace record

alguma ideia do que pode estar acontecendo?
