Perf top - warning perf not found for kernel
5,943
I'm unfamiliar with your particular kernel version which tells me that are either trying to install software for an unsupported release and should likely upgrade or your running a custom kernel. All I can tell you with any certainty is that perf
is in the tools directory of the kernel source tree and that you can obtain the sources for your major version of the kernel here.

I downloaded perf program for Ubuntu using this command:
sudo apt-get install linux-tools-common linux-tools-generic
But when I try perf top it gives me this
WARNING: perf not found for kernel 4.9.78-xxxx You may need to install the following packages for this specific kernel: linux-tools-4.9.78-xxxx-std-ipv6-64 linux-cloud-tools-4.9.78-xxxx-std-ipv6-64 You may also want to install one of the following packages to keep up to date: linux-tools-std-ipv6-64 linux-cloud-tools-std-ipv6-64
I tried running
sudo apt-get install linux-tools-4.9.78-xxxx-std-ipv6-64
But it doesn't work.
I tried
sudo apt install linux-tools-std-ipv6-64 linux-cloud-tools-std-ipv6-64
But I got
E: Unable to locate package linux-tools-std-ipv6-64 E: Unable to locate package linux-cloud-tools-std-ipv6-64

davidbaumann over 6 yearsTry
apt install linux-tools-std-ipv6-64 linux-cloud-tools-std-ipv6-64
, this is version independent and will work for later kernel updates. -

edward over 6 yearsI tried locally on a 4.4 kernel and perf worked perfectly. But on 4.9.78 this is still an issue. I cannot run more tests on the real machine which has the issue as I could be jeopardizing alot of valuable files which I don't want to loose. But perhaps I can download that kernel on my local machine and give it a try, or if someone from this community has a solution / possibility to do the same, that would be essential. Thank you though for the comment

Elder Geek over 6 years@edward If you aren't backing up you are already jeopardizing valuable files. If you have a tested and true backup and restore procedure, you can try whatever you like. Feel free to drop me a comment when you have accomplished this and I may be able to add some clarity to my answer.
