This is insane, perf is not working in the latest and greatest ubuntu ... I too verified that it is missing 6.14.xxx

Today I got an update of Linux Kernel, v6.14.0 packages. Previously I had to use 6.14 kernel installed from custom .deb packages as described here https://bugs.launchpad.net/ubuntu/+source/linux- firmware/+bug/2102029 (comment #24). Otherwise my Wi-Fi card didn't work. I tried to use `perf` but got an error: ``` $ perf -v WARNING: perf not found for kernel 6.14.0-24 You may need to install the following packages for this specific kernel: linux-tools-6.14.0-24-generic linux-cloud-tools-6.14.0-24-generic You may also want to install one of the following packages to keep up to date: linux-tools-generic linux-cloud-tools-generic ``` The suggested packages *are* installed. `uname -a` says I'm using the right kernel. The one installed before was 6.14.3 - I booted using the right one and removed 6.14.3 packages. Also I tried to reinstall the *-tools* packages, but it didn't help. For me as a C programmer having `perf` is quite important. At this point I don't know how to debug this further. If there is anything else I can do to help diagnose the issue please let me know.
