Not able to run perf on Linux 4.4 kernel (Ubuntu 15.10)

I'm not able to run perf on linux 4.4. I'm using ubuntu 15.10.

The error I'm getting is:

Code:

WARNING: perf not found for kernel 4.4.0

You may need to install the following packages for this specific kernel: linux-tools-4.4.0-4.4.0 linux-cloud-tools-4.4.0-4.4.0

You may also want to install one of the following packages to keep up to date: linux-tools-4.4.0 linux-cloud-tools-4.4.0

I also tried to install linux-tools specific package and even then I'm getting the same error. Am I doing something wrong here?

perf-trace

PERF-TRACE(1)							    perf Manual 						     PERF-TRACE(1)

NAME

       perf-trace - strace inspired tool

SYNOPSIS

       perf trace

DESCRIPTION

       This command will show the events associated with the target, initially syscalls, but other system events like pagefaults, task lifetime
       events, scheduling events, etc.

       Initially this is a live mode only tool, but eventually will work with perf.data files like the other tools, allowing a detached record
       from analysis phases.

OPTIONS

       -a, --all-cpus
	   System-wide collection from all CPUs.

       -e, --expr
	   List of events to show, currently only syscall names. Prefixing with ! shows all syscalls but the ones specified. You may need to
	   escape it.

       -o, --output=
	   Output file name.

       -p, --pid=
	   Record events on existing process ID (comma separated list).

       -t, --tid=
	   Record events on existing thread ID (comma separated list).

       -u, --uid=
	   Record events in threads owned by uid. Name or number.

       -v, --verbose=
	   Verbosity level.

       -i, --no-inherit
	   Child tasks do not inherit counters.

       -m, --mmap-pages=
	   Number of mmap data pages. Must be a power of two.

       -C, --cpu
	   Collect samples only on the list of CPUs provided. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges
	   of CPUs are specified with -: 0-2. In per-thread mode with inheritance mode on (default), Events are captured only when the thread
	   executes on the designated CPUs. Default is to monitor all CPUs.

       --duration: Show only events that had a duration greater than N.M ms.

       --sched: Accrue thread runtime and provide a summary at the end of the session.

       -i --input Process events from a given perf data file.
