CICFlowmeter tcpdump Permission denied

Im trying to install TCPDUMP_and_CICFlowMeter from this CICFlowmeter

my server is Ubuntu, my steps was

root@testbed-ml-node:~# git clone https://github.com/iPAS/TCPDUMP_and_CICFlowMeter.gitroot@testbed-ml-node:~# cd TCPDUMP_and_CICFlowMeter/root@testbed-ml-node:~/TCPDUMP_and_CICFlowMeter# nano try_me.sh

I edit the file try_me.sh

capture_interface_pcap.sh wlan0 pcap

Then To Fix the Permission Denied Problem, add the following line into file /etc/apparmor.d/usr.sbin.tcpdump:

/usr/sbin/tcpdump {  #...  # for -z  /**/* ixr,        # <-- add me!  #...}

Also, To Fix java.lang.UnsatisfiedLinkError Problem

sudo apt install libpcap-dev

Then i run the script

root@testbed-ml-node:~/TCPDUMP_and_CICFlowMeter# ./try_me.sh 

i Get error
