It's on the right track but I wonder how to pin-point exact reason and solution.
I have seen spelling mistakes cause this, but yours seems fine.
Can be the old network driver not unloading.
It's along those lines, the master can not get control over the network interface.
Can you set debug "ethercat debug 1", restart the ethercat server and show the dmesg again?

I can't enable debug mode. Could this be part of the problem?

Yes debug is switched on. But restart the master "sudo service ethercat restart" so one can see messages from the startup of the server and hopefully figure out why it doesn't take control over the network interface.

I did the following:
ethercat debug 1
sudo service ethercat restart
sudo dmesg
The log file says the following:
[ 5.747038] ec_master: loading out-of-tree module taints kernel.
[ 5.748211] ec_master: module verification failed: signature and/or required key missing - tainting kernel
[ 5.765973] EtherCAT: Master driver 1.6.4 1.6.4.g703b611-1+17.1
[ 5.766146] EtherCAT: 1 master waiting for devices.
is that the problem?

Mine looks like
so my installation goes on and loads the ec_generic module from igh ethercat.
And thinking of your "tainted kernel" message, do you actually have the ethercat network drivers installed?
I search for them here and find them as below
[ 3.850145] EtherCAT: 1 master waiting for devices.
[ 3.868627] ec_generic: EtherCAT master generic Ethernet device module 1.6.3 1.6.3.g805e407-1+15.3

[ 3.892744] EtherCAT 0: Starting EtherCAT-IDLE thread.And thinking of your "tainted kernel" message, do you actually have the ethercat network drivers installed?
I search for them here and find them as below

Search for the ec_generic.so files like I did.
