Installing ethercat repositories

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 error I 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 warning fix 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

Have you tried my fix above? sound like you have the same problem as me.

2. When running the "sudo apt update" I get this error

Code:

E: Conflicting values set for option Signed-By regarding source http://download.opensuse.org/repositories/science:/EtherLab/Debian_12/ ./: /etc/apt/trusted.gpg.d/science_EtherLab.gpg != /etc/apt/trusted.gpg.d/science_EtherLab.gpg.key.binary.gpg E: The list of sources could not be read. I fixed it by editing the [b]/etc/apt/sources.list.d/science_EtherLab.list, changing "[i]science_EtherLab.gpg.key.binary.gpg" to "[i]science_EtherLab.gpg"[/i][/i][/b]

 

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 was able to edit the file by using: Then it all worked.  Thanks for the notes.

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.

Also having problems installing and building Ethercat Master. I have tried the first script at the top ofthe thread(editing Deb12 for Deb13) and the new updated script and still get SSL errors, listed below.
Linux headers are installed and latest for rt kernel.
