Ethercat installation from repositories - how to step by step

@TntMold, @sockheavan,
Please follow this sticky if you repositories are not installing
forum.linuxcnc.org/ethercat/53785-instal...thercat-repositories

Unfortunately, there are licencing and legal implications that prevent Linuxcnc from doing what Grotius did.
If the developers do not deploy the changes to the ISO I have made on my request, These issues will continue.
 

I wonder what Grotius did that can have such implications. After all it wasn't long ago we used to download and compile the ethercat master ourselves when we needed it.

Anyways, I have installed ethercat from repositories a few times the last few months and always ran into this with the signing and expired key. And the last time on 2.9.3 iso the ecat.sh didn't solve it. Can we have a pointer in the first sticky to the third sticky? I had a hard time finding the ecat.sh script to start with.

The ecat.sh script, admittedly I may have screwed some things up, did add a duplicate entry in /etc/apt/sources.d. The original was call ScienceLab-something. I removed that one. Then there was the question of where the new downloaded key went. Kind if forgotten the details but there became duplicate keys and one had to be removed.

In the end I wonder if it isn't easier to just remove the signed-by entry in the sources file. So now I only have this in the igvh.sources file

I am very new to Linux and this is obviously an ignorance problem. Why can't I run the script?

Dear jjdege.
How can you solve the error when you install the ethercat package by command "sudo apt install -y linux-headers-(uname -r) ethercat-master linuxcnc-ethercat?

there is an error in the command try this, it doesn't give me any errors
