I tried running the script on a fresh LCNC 2.9.3 install from ISO and encountered a few problems.
1. Command not found error when running "sudo ./ecat.sh"
Fixed by running "chmod +x ./ecat.sh" before
2. When running the "sudo apt update" I get this errorI fixed it by editing the /etc/apt/sources.list.d/science_EtherLab.list, changing "science_EtherLab.gpg.key.binary.gpg" to "science_EtherLab.gpg"
3. After re-running "sudo apt update" I get this warningfix it by removing the ighvh.sources file by running "rm /etc/apt/sources.list.d/ighvh.sources"
After all that, I was able to follow Rodw instruction and successfully install Ethercat. I don't know how to code and this is my first time using Linux, so I don't know if this is the correct way to fix these problems, but I hope it at least helps other people with the same problem.

Thanks that works for me too! The thread "Ethercat installation from repositories - how to step by step" is getting really long. I tried a lot of things suggested there to no avail. Eventually did a new ISO install LinuxCNC 2.9.3, ran the ecat.sh script, and changed the things you mentioned. I then followed the main installation thread and got it to work.
I'll write a new installation instruction webpage for my customers. That will save them a lot of frustration.

I am currently installing Linuxcnc 2.93 on a PC. After the installation I run "sudo apt update". It tells me that the Ethercat repos have errors. After running the script, "Apt" is broken because no package can be installed. How do I update the necessary sources? I am new to Linux cnc.
thanks Markus
many thanks Burnie it's work

I'm getting this same error. But when I try to edit the file, it says I don't have permission.
I tried going to that directory and using chmod +x ./science_EtherLab.list, but that didn't work.
How do you edit the file?

I have been trying to install ethercat using the step-by-step instructions for a month and nothing is working. I have erased my partition and reloaded at least 20 times, but there is always a roadblock: broken links or unmet dependencies or it can't find the repositories.
My downloaded iso file installs debian 10 and linuxcnc 2.8.4
My current error is:
The following packages have unmet dependencies:
linuxcnc-ethercat : Depends: libc6 (>= 2.34) but 2.28-10+deb10u4 is to be installed
I am either getting closer or just circling the drain, any help would be appreciated.
when I try to update libc6 it tells me the most recent version is 2.28-10+deb10u4 which is clearly older than what ethercat installation wants. How do I get to success?

Maybe get a newer Debain version?
2.28 is the last version in debain 10
Linuxcnc 2.9 comes in Debain 12

If you are still having problems installing, I suggest you first uninstall all possible previously installed keys and repositories:
and then run the script from the first post.
Or you can run the updated script, which will do this immediately. I've attached it.
sudo rm -f /etc/apt/sources.list.d/ighvh.sources /etc/apt/sources.list.d/linuxcnc-ethercat.list /etc/apt/sources.list.d/science_EtherLab.list /etc/apt/trusted.gpg.d/linuxcnc-ethercat.gpg /etc/apt/trusted.gpg.d/science_EtherLab.gpg*and then run the script from the first post.
wget -O ecat.sh https://forum.linuxcnc.org/media/kunena/attachments/20660/ecat.sh.txt
chmod +x ./ecat.sh
sudo ./ecat.shOr you can run the updated script, which will do this immediately. I've attached it.
wget -O ethercat-repos-update.sh https://forum.linuxcnc.org/media/kunena/attachments/34171/ethercat-repos-update.sh.txt
chmod +x ./ethercat-repos-update.sh
sudo ./ethercat-repos-update.sh
