我最近必须更新内核才能使用显卡。现在我想使用 perf,但它尚未安装。我收到以下消息:
You may need to install the following packages for this specific kernel:
linux-tools-5.11.0-051100-generic
linux-cloud-tools-5.11.0-051100-generic
但是,当我尝试安装这些软件包时,我收到以下消息:
E: Unable to locate package linux-tools-5.11.0-051100-generic
E: Couldn't find any package by glob 'linux-tools-5.11.0-051100-generic'
E: Couldn't find any package by regex 'linux-tools-5.11.0-051100-generic'
和
E: Unable to locate package linux-cloud-tools-5.11.0-051100-generic
E: Couldn't find any package by glob 'linux-cloud-tools-5.11.0-051100-generic'
E: Couldn't find any package by regex 'linux-cloud-tools-5.11.0-051100-generic'
我在哪里可以找到这些包/如何添加这些包?
