This is one cmd in one line and there was a failure from my side

This is ok, because the system can not verify the key.

libethercat-dev libpdserv3 libpdserv3-dev librtipc  librtipc-dev
 etherlab2 testmanager-ng

You can copy it to /etc/ethercat.conf

That is correct, because the kernel modules are managed by dkms
have a look at 
/lib/modules/KERNELVERSION/updates/dkms/

It is not so bad, the basic work is done:
-Master is running,
-Network device is attached
-You have basic communication over the fieldbus.
- You get output for sudo ethercat ma
- You get output for sudo ethercat sl
- System is ready to start an application.
- Next step is to compile your etherlab model against the correct
system headers.
- Please check /usr/local for old installation files of etherlab and
pdserv.
