Installing ethercat repositories

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.

SSL errors:

Can anyone help me put this right please?

##Fresh start, reinstalled## 

Tntmold: I think you have to build LinuxCNC from source for an Ethercat install, then build Ethercat master. It will not work from the downloaded ISO file.
Build from a Debian13 Netinstall(or full) image.

It does work, RodW did a lot of work for that to work
forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step

I stand corrected, and somewhat outdated!

There are still some reasons why its necessary to build the Ethercat master from source which is pretty easy anyway. In that case, go to the etherlab site, get their source and read their instructions in the PDF instructions
etherlab.org/en_GB/ethercat

@NIckH, the Etherlab repository also hosts the latest Ethercat hal driver thanks to Scott Laird. So it is possible to install everything without building anything!
