I tried to run JBOSS(v5.x)[ubuntu 18.04] and it was saying:

Deployment "WebServer" is in error due to the following reason(s): LifecycleException: Protocol handler initialization failed: java.net.BindException: Address already in use /0.0.0.0:8443
Deployment "jboss.web:service=WebServer" is in error due to the following reason(s): ** NOT FOUND Depends on 'jboss.web:service=WebServer' **

So, tried to kill that process. To find the PID, used command lsof -i:8443 and found no process. Then tried sudo lsof -i:8443 and got this:

COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
lxd     11526 root   22u  IPv4 696227      0t0  TCP localhost:8443 (LISTEN)
lxd     11526 root   25u  IPv4 699223      0t0  TCP localhost:41776->localhost:8443 (ESTABLISHED)
lxd     11526 root   26u  IPv4 701114      0t0  TCP localhost:8443->localhost:41776 (ESTABLISHED)

Then ran sudo kill -9 11526 //as without sudo, it was saying operation not permitted.

But again, when I run sudo lsof -i:8443 I can see new PID(each time I kill it, it runs in another PID!)
I am not sure what is wrong here and what to do.

The ports have been occupied by the lxd container service.

To see your running containers:

lxc list

If nothing is running, the lxd daemon can be closed with:

lxd shutdown

This should free up the ports.
