problem with running ethercat

hello guys,
i get this error when i try to run these commands
(venv) abdulkareem@debian:~$ ethercat slaves
Failed to obtain number of masters: ioctl() version magic is differing: /dev/EtherCAT0: 37, ethercat tool: 33
A probable reason is that the command-line tool
you are using is built with a different
source code version than the currently loaded
kernel module. Please install an updated version
of either the tool (ethercat) or the kernel
module (ec_master.ko).

when i try to update i found also this error which i think it may cause the above error

(venv) abdulkareem@debian:~$ sudo apt-get update

can anyone help me with this error ??

The problem with `ethercat slaves` is presumably because your kernel is running a different version of the EtherCAT code than the one that the `ethercat` command-line tool expects. If you'd recently installed an update without rebooting, then I'd expect to see the kernel version lower than the command-line version, but that's not what I see here. So that's kind of odd. The best fix would be to update and reboot. But...

IIRC they recently changed the keys for the OpenSUSE build server. I *think* the instructions in forum.linuxcnc.org/ethercat/45336-etherc...ep-by-step?start=290 should fix this. Try that, and if it runs successfully then reboot and see if everything works?

Seems like you are running a python virtual environment. Not sure that is an issue, but Try after exiting it.
