Ethercat installation from repositories - how to step by step

Looking at the above post, I don't recall installing headers separately. Maybe that is it.

These are also needed to install anything with dkms like the Realtek r8168-dkms network driver.

hello rod,
can you help me locate ethercat-master folder from where is installed ethercat-master on your hybrid.iso file... I need to change network drivers if it is possible... is it possible to change it please?

I don/t install anything, we just set up the ethercat repositories in /etc/apt here
github.com/LinuxCNC/linuxcnc-live-build/...worm/config/archives
 

So having reinstalled I'm back to the point of halcmd loadusr running, and 'show pins' showing the two entries from RodW' ethercat-conf, but none of my pins showing. Running 'ethercat sIaves -v' shows nothing also; I have one servo connected.
Maybe my ethernet connection though I'm sure I have the right interface in ethercat.conf. Any ideas?

Endian, the issue you're experiencing with

dpkg: error processing package ethercat-dkms (--configure):
 installed ethercat-dkms package post-installation script subprocess returned error exit status 10
dpkg: dependency problems prevent configuration of ethercat-master:
 ethercat-master depends on ethercat-dkms; however:
  Package ethercat-dkms is not configured yet.

Is because the ethercat-dkms package was recently broken it appears (July 26th)
The deb file is missing the fake_lib folder inside, but the Makefile/configure scripts are expecting it to still exist.
You can see this in the `/var/lib/dkms/ethercat-dkms/1.6.1/build/make.log`

I had to manually download the fake_lib from the origin ` gitlab.com/etherlab.org/ethercat `
I then had to move it into `/var/lib/dkms/ethercat-dkms/1.6.1/source`, run `sudo make`, then run `sudo dpkg --configure ethercat-dkms` to forcibly re-configure the dkms package.

I then ran the standard linuxcnc-ethercat install and it no longer complained about the DKMS package.

For a more proper fix, you'll need to wait for the package maintainer to release a new package version without the issue.

   good morning, I'm new to linuxcnc, I tried following all the steps described in the guide but I can't install ethercat on linuxcnc, I always get the same errorWhat could it be that it can't find the necessary files. Where am I wrong

1. Does the PC have an internet connection?
2. Do in a terminal " sudo apt update " before trying to install

Yes, the PC has an internet connection, running the sudo apt update command, which I did before, gives me this error

There appears to be something broken at ethercat themselves.
