Hi Rod,

I followed these instructions several times  and, everything worked perfectly. Tried to install today and I get an error saying that no public key is available. Any idea if something has something changed? This is a fresh install of the Debian buster Linuxcnc iso.

Kind regards,
Dan

Looks like ARM is not supported in their repo; You will need to compile from source

Just had this issue the other day. I don't think you have to compile from source if you don't want to. I'm on a Raspberry Pi 5.

It looks like EtherLab changed the name of their distribution repo from IgH to EtherLab. Check out the new location on this page under the Debian section.
etherlab.org/en_GB/getting-started

Relevant instructions:
export KEYRING=/usr/share/keyrings/etherlab.gpg
curl -fsSL download.opensuse.org/repositories/scien...ebian_12/Release.key | gpg --dearmor | sudo tee "$KEYRING" >/dev/null
echo "deb [signed-by=$KEYRING] download.opensuse.org/repositories/science:/EtherLab/Debian_12/ ./" | sudo tee /etc/apt/sources.list.d/etherlab.list > /dev/null
sudo apt-get update

You will have to remove the sources list of IgH if you don't want errors during apt updates.

I don't know if you guys rebuild images between releases, but if it's possible to remove the IgH repo in favor of the EtherLab it may be helpful.

Hello.
Today I reinstalled the Ethercat driver with the command "sudo apt install ethercat-master libethercat-dev linuxcnc-ethercat". Before that I deleted the old driver that was installed in the system.
Now the system does not work and gives an error as in the photo. Please help me with advice on what I should do to restore the system's functionality. Previously, there was driver 1.5.2.
Thank you, I really hope for your quick help.

just a guess, try:

sudo dpkg-reconfigure ethercat-dkms

Thank you very much

I have a question: I have already installed ethecat and linuxcnc-ethercat. With the command sudo systemctl status ethercat.service I see that the service is running. With the command ethercat master I try to see which master is configured and I get the error: Failed to obtain number of masters: ioctl() version magic is differing: /dev/EtherCAT0: 37, ethercat tool: 30

The question is: do I necessarily have to have a device connected that supports ETHERCAT to confirm that I have everything installed correctly, or why does this error appear and how to solve it?
