是否可以使用5.4.39内核在ubuntu上安装perf？

Question

我想用5.4.39内核在ubuntu20.04上安装perf。

问题是我得到了

root@xxx:/home# perf

WARNING: perf not found for kernel 5.4.39

  You may need to install the following packages for this specific kernel:
    linux-tools-5.4.39-linuxkit
    linux-cloud-tools-5.4.39-linuxkit

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

然后，当我试图安装这些软件包时，会说：

E: Unable to locate package

Answer 1

尝尝这个。

打开终端并运行：

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install --reinstall linux-tools-common linux-tools-generic linux-tools-`uname -r`
