我无法运行“perf”命令。Perf 是一个用于堆栈跟踪的 Linux 分析器

Question

尝试使用性能分析器。我已经安装了 linux 通用工具，但没有运气。这是我收到的消息：

---

r@r-K55A:~$ perf
WARNING: perf not found for kernel 3.16.0-45

  You may need to install the following packages for this specific kernel:
    linux-tools-3.16.0-45-generic
    linux-cloud-tools-3.16.0-45-generic

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

我尝试安装上述软件包，但出现以下错误：

---

Unable to locate package linux-tools-3.16.0-45-generic
E: Couldn't find any package by regex 'linux-tools-3.16.0-45-generic'
